@Coward_Token The 1/1 Koma, Cosmos Serpent would still be legendary and one of them should be sacrificed. Am I missing something?

Irenicus's Vile Duplication seems like an awesome addition, thank you!

In Simic there are options like Koma, Cosmos Serpent which can just overwhelm tables by itself, especially if you can protect it. Not the cheapest card though, some cheaper options are Overwhelming Stampede, which can help close games by making your creatures a lot bigger, even if you don't have a huge number of them, as long as you have a creature with decent power out you'll be good. There is also Blossoming Bogbeast, this wants ways to gain life, but Green has some out there, Primal Command is a great budget card IMHO, solves problems and has pretty impressive synergy with the Bogbeast. You might like using Spawning Kraken, any time an appropriate creature gets in you get another big token. Finally, not sure if you have enough Islandwalk, but Stormtide Leviathan is a big unblockable attacker that makes you fairly hard to attack. Resolving any of those cards tends to end games pretty quickly in my experience, and most reward you for simply having a big board, a thing you always want to be doing.

I also like some of Blue's fairly nasty interaction, one alternative to making your guys big is to make someone else's guys way smaller, Mass Diminish is frankly an absurd amount of value in more Casual pods, such as lower budget games. Note it has Flashback and the effect lasts an entire turn cycle, meaning it can also eliminate an archenemy that's gotten ahead. Since you're running higher MV stuff, you might try out Curse of the Swine, this can make your opponent's defenses quite paltry, and it also can deal with problem creatures (like the aforementioned Koma) since it's an Exile effect. Another way to chip away at your opponent (and empower yourself) is to use something like Mass Diminish, I don't know how long your games go, but if you expect to end up with +10 mana available, this card starts looking interesting. I'd skip it if people run a lot of counterspells though, it's a 'go big or go home' kinda card but by all means hold up your own Negate.

Green has some interaction of it's own, if people run flyers in your meta and you're losing to them there are many ways in Green to wipe them, I like Squallmonger and Silklash Spider, but there are a ton more including Hurricane. If you don't have many flyers, this does nothing to you. Green also has Ezuri's Predation if people like to make lots of tokens that are usually smaller than 4/4 (if you run anthem effects that affect the beasts the card is much better obviously).

Just a general point, in Simic it's nice to avoid artifact ramp because you have so many amazing options to ramp with, artifacts tend to die more easily than lands, so effects that get extra lands into play are better than Command Sphere, especially in a 2 colour deck I'd argue. Myriad Landscape and Blighted Woodland are both fairly interesting ramp cards, you can always leave them as lands until you need them. Another feature of land ramp is that you can run cards like Rampaging Baloths and Scute Swarm, either gets a lot better if you're getting more landfall trigger, artifacts rarely have synergy with Simic game plans.

Profet93 - I see where you're coming from but the 3 power is key for this deck as the Coil Tokens that Koma, Cosmos Serpent makes are all 3/3's. Also since I'm in Green/Blue Garruk's Packleader being a creature has some upside as it can be found with the few tutors I'm running.

Specific example: I have Runadi, Behemoth Caller on the field and Koma, Cosmos Serpent in Hideaway with Mosswort Bridge. If I activate Mosswort and play Koma, does that trigger Runadi?

Last game of the year! Sorry I've taken over your comment board, hope all these gameplay interactions help!

Opponents: Koma, Cosmos Serpent, Muldrotha, the Gravetide, Tevesh Szat, Doom of Fools / Armix, Filigree Thrasher

Starting Hand: Marsh Flats, Plains, Sol Ring, Serra Ascendant, Serra Avenger, Court of Grace, Breathkeeper Seraph

T1 - Marsh Flats into Plains into Serra Ascendant

T2 - Plains into Sol Ring and Luminarch Ascension (drew into), swung in for 6 damage

T3 - Plains into Court of Grace, drew on endstep, swung in for another 6 damage

T4 - +1 Angel on upkeep, Plains into Giada, Font of Hope and held up mana to make 2 Angels, drew on endstep, swung in for another 6 damage

T5 - created 2 Angels (6 power & 7 power) on opponents end step, +1 Angel (8 power) on upkeep. Cast a Tome of Legends getting ready for the boardwipe. Swung in for 21 damage, drew on endstep.

T6 - nobody at the table had the boardwipe so I cleaned up next turn with Sigarda's Vanguard knocking out each other player simultaneously. I think this was the fastest this deck has ever performed in a 4-man pod and all the damage was dealt by me.

Opponents: Koma, Cosmos Serpent, Muldrotha, the Gravetide, Tevesh Szat, Doom of Fools / Armix, Filigree Thrasher, O-Kagachi, Vengeful Kami

Starting Hand: Windswept Heath, Arid Mesa, Plains, Bonders' Enclave, Serra Paragon, Gisela, the Broken Blade  Meld, Archangel of Thune

Thought about not including this one either as it was a slow hand and a fast game. Muldrotha comboed out turn 4 making 2 million squirrels and nobody had any interaction so we were dead on turn 5.

Opponents: Koma, Cosmos Serpent, Muldrotha, the Gravetide, Tevesh Szat, Doom of Fools / Armix, Filigree Thrasher, O-Kagachi, Vengeful Kami

Starting Hand: Nykthos, Shrine to Nyx, Plains, Plains, Pyre of Heroes, Gisela, the Broken Blade  Meld, Battle Angels of Tyr, Angelic Curator

I had played Battle Angels of Tyr but it was quickly removed by Tevesh before I could swing with it, which is fair given a 5-man pod.

Instead I went for the slower play with Giada, Font of Hope, Angelic Curator and Angelic Sleuth on the field. I held Pyre of Heroes in hand thinking I would go for the Inspiring Overseer / Serra Paragon line to draw into some cards and get some clues.

However, Muldrotha again was a huge problem turn 5. They had Scute Swarm and cracked some fetches and played green ramp spells bringing up their total to the low 100s but they only had 32 they could attack with. They decided to swing all of them at me as I was the only one with any sort of board presence. O-Kagachi let the table know they had a fog effect but we elected to use it on the next turn.

At this point I had Giada, Font of Hope, Angelic Sleuth, Righteous Valkyrie and Pyre of Heroes on the battlefield. Once Muldrotha had started producing massive amounts of Scutes I knew they were coming at me. Also I had drawn into Archangel of Thune which I played and swung in bringing me back up to the low 20's.

On turn 6 O-Kagachi used the fog and Muldrotha just set themselves up better for the next round. They cast a Sandwurm Convergence to stop me from knocking them out.

Tevesh decided this was the best time to go off so they tapped out for a Peer into the Abyss. A lot of artifact shenanigans happened and they ended up at 4 life due to Bolas's Citadel, nearly wiped the board with Ugin, the Spirit Dragon and killed Muldrotha with an artifact creature with Cranial Plating and Lightning Greaves. Unfortunately they didn't see that O-Kagachi was out and only -5 for Ugin so they were dead to the dragon on their turn.

I was able to build back relatively quickly as I drew into a Thorough Investigation and cracked some clues. O-Kagachi became the new archenemy as they had their commander out and a Fist of Suns so they were casting high-costed cards with the limited mana they had. Koma used Kiora, the Crashing Wave to negate the damage of O-Kagachi's commander. They also countered a Conflux which could've ended the game.

I tried to swing in once but was stopped by a fog. I also made another misplay with Oblation targeting their Myojin of Seeing Winds as I misheard thinking it was a 10/10 flying indestructible when it was a 3/3 that didn't even fly. They removed the divinity counter drawing 12 and drew another 2 off Oblation. Next turn they cast a Morophon, the Boundless and dropped all the spirits they drew off those 14 cards. If I had held up my Oblation for their fist of the suns instead they would have had no mana for anything else and I could've swung in for the win.

Luminarch Ascension finally popped off! When unanswered it just ends games. Even with a boardwipe it can refill the board with mana. With Giada out it adds lethal threats quickly. I understand that it may not have the surprise factor but I think the resiliency is more important here. As you've mentioned before, not a lot of people run enchantment removal as creature removal is preferable which means this has staying power.

Court of Grace was also amazing here. While 1 card a turn is not the best for 4 mana, 1 card and 1 angel for 4 is amazing. Obviously the Sol Ring did work in getting it out early but against slower decks they had no way to attack me regardless.

Pyre of Heroes was actually useful this time! Pitching the 2/2 body of Angelic Curator into a Righteous Valkyrie is a strong move. I was only able to use it once before the Ugin exile but it helped keep me in the game. Without it, I would've been dead right after Tevesh finished off Muldrotha, perhaps even in the same turn.

Sigarda's Vanguard was also great again. However if I'm not planning out dropping my angels out in the correct turn order then I'm not always getting the full benefit from her. Akroma's Will would save us the headache of counting and planning while also providing the evasion to get through flying creatures. I think I'll still stick the Vanguard as the light recursion package allows us to bring her back on another turn for additional value whereas Will would just languish in the graveyard.

We had a turn 0 discussion before games 2 and 3 and agreed on playing more mid-tier decks as I only brought Giada. The Muldrotha player typically durdles with nothing to do and decided to add in some spicy cards not knowing how they'd perform. Tevesh doesn't always go off like this but Peer into the Abyss is usually a card that gets countered. The table let it resolve due to needing to knock out Muldrotha first.

Yeah, in my playgroup, since Koma, Cosmos Serpent is fair game - Mob Rule & other mass control grabbers are fair game. But, my favorite thing with Extus, Oriq Overlord  Flip is versatility & differences of buildability. I also like how you can sub strategize more effectively with him than other hyper-focused decks. For exampl,e I have changed my whole focus for a game by starting with a Shadowspear in hand - that puppy is hilarious strapped onto a blood avatar. Or I have started with a sword of x/y & actually started with the Extus side just because of double-striking sword-wielding commander is a solid way to go.

Was able to squeeze in a 4-pod game after Brother's War Game Day today and had some interesting interactions with the new cards:

Opponents:

Wilhelt, the Rotcleaver Zombies, Koma, Cosmos Serpent Simic Goodstuff, Krenko, Mob Boss Goblins

Starting Hand:

Ancient Tomb, Mutavault, Cavern of Souls, Snow-Covered Plains, Enlightened Tutor, Sephara, Sky's Blade, Bishop of Wings

I didn't have a draw in hand but with the tutor could've gotten one. First card I drew though was Smuggler's Share so it went something like:

T1 - Snow-Covered Plains for Enlightened Tutor for Pearl Medallion

T2 - Ancient Tomb into Smuggler's Share *

*I know I broke the carnal rule of not playing Giada turn 2 but I was fully expecting the Koma player to begin ramping as Simic typically does

T3 - Cavern of Souls into Pearl Medallion & Giada, Font of Hope

T4 - Snow-Covered Plains (drew into) to play Bishop of Wings and then I had to replay Giada for 3 because the Krenko player had PTSD from the angel swarm I played against him last time and blew up my Giada

My first angel to drop after Giada was actually Breathkeeper Seraph who I soulbonded to Giada. My Bishop of Wings was also blown up by Krenko but when they took out Giada, I just got her back on my next upkeep and re-soulbonded her.

I was able to get out Sephara, Sky's Blade hardcasted with an Angelic Page for 1 and had a nasty board state. Since nobody was playing white, they didn't have many exile effects, only destroy effects. Even if they were able to take out Sephara, they'd need to follow up with a board wipe before my upkeep or I'd just get her back. Wilhelt played Drag to the Bottom which only ended up helping me since my angels were so large.

In the end I closed out the game with a couple swings and a well timed Sigarda's Vanguard not that it mattered much since they couldn't touch my board. One play I enjoyed was using Oblation on Koma before their turn as they never ended up ramping and could never get their commander back out. I had misgivings about this card but it ended up being useful and I don't always have a Path or Swords in hand to deal with threats. Smuggler's Share was yet another whiff this game as I only got a single treasure out of it and it lasted the whole game. I think the lesson here is that I should always use Enlightened Tutor on a draw spell, rather than a ramp spell. On the other hand, if no player is ramping or drawing then we're essentially just keeping pace with them.
