Act of Treason Discussion

Kogarashi on skyfire kirin and The lack ...

Incorrect, Sousaphonist.

Summoning sickness refers to the rule that a creature cannot attack or use activated abilities with the or symbol in their cost if it hasn't been continuously controlled by a player since the beginning of that player's most recent turn. (See rule 302.6)

So say you cast Llanowar Elves on turn one. It has summoning sickness because you haven't controlled it since the start of your turn (beginning of the untap step). Three turns later, I use Act of Treason to take control of it during my first main phase. Now I control it. I haven't controlled it since the start of my untap step, so normally it would have summoning sickness, but Act of Treason gives it haste. I can use Elves' mana ability or attack with it this turn.

Now let's say that on the next turn, I steal it again, but this time with Skyfire Kirin 's ability. Again, I haven't controlled the creature since the start of my untap step, but unfortunately in this case, Kirin doesn't give the Elves haste. I can't actually use its mana ability or attack with it this turn unless I've got something else to give it haste.

A creature will keep regaining summoning sickness if control of it keeps getting interrupted. This could be control-changing effects like the above, but it also includes zone-changing effects (such as flickering with Ghostly Flicker ). This is why so many short-term control-changing effects (usually in red) add haste, so you can use it before you hand it back to its previous controller. Skyfire Kirin is an odd one out.

Saheeli is part of an infinite combo with Felidar Guardian , it blinks saheeli herself to keep doing the minus ability over and over. I think the deck uses Serum Visions and Opt . iunno

Anyways, Act of Treason could help lower that Volition Reins ... not to mention splashing black for Viscera Seer to sac their dudes

Lightning Bolt is a 3-of on average with pros

I would cut green and consider running Arcanis the Omnipotent . He is a good card draw engine and your deck looks like it can handle the high mana cost. I would also recommend cards that temporarily steal opponent’s creatures, like Act of Treason . Of course, you would have to adjust your mana base slightly, especially if you do cut green, but these are the things that I would recommend.

did some awful calculating and this is a 25-lander

Act of Treason seems like a reasonable replacement for some of the all-swipes

but mainly, splash black for Viscera Seer

oooOOOOooo... that's cool. Though, I wonder if you confused how equipment work with how auras work? Equipment stays - as if it were dropped. Auras are destroyed, as though they were spiritually bound to the living forces of the being. So I wonder if Hex would be more appropriate for auras? Than again, auras can target any creature. Equipment can only be attached to creatures you control, unless you can circumvent it with something such as "Attach" rather than "Equip", or equip it to a creature under the influence of Act of Treason and give it back.

Regardless, seems like a fun challenge. Reminds me of Thirsting Axe.


Vampire's Bite

Tribal Equipment - Vampire

Equipped creature has lifelink. If equipped creature is a Vampire, it also gains +2/+0.

At the beginning of equipped creatures owner's post-combat main phase, if this creature didn't deal combat damage to an opponent, its controller sacrifices that creature and return Vampire's Bite under it's owner's control.

Equip

Hex: Pay 3 life


Make another Hex card.

rdean14, if you gain control of it only until the end of your turn, does that ability also last only until the end of your turn? If so, you won't have it during your upkeep to deal the 1 damage to you.

Otherwise, that creature will just continually ping you for 1 damage turn after turn, and you only got to use it once. I feel like you might be missing some wording there :p


Path of Savagery

Sorcery

Gain control of target creature until end of turn. Untap it, it gains haste and your choice of doublestrike or trample until end of turn.

Gratuitous, ruthless, unrelenting, untamed, loud. Words can describe them, but only by witnessing their aftermath can you truly understand them.


Not to pat myself on the back too much here, but damn I love that flavor text <3 God, I wish I could see this as a real card. Hey, I gotta live up to my name sometimes, right? :3

Kogarashi on In EDH, What color can ...

Unless the Krenko, Mob Boss player somehow ends up in control of a permanent with a black mana symbol in its cost (such as through Act of Treason), Nykthos, Shrine to Nyx can't produce black mana due to Krenko's player having zero devotion to black. Because Nykthos can't produce it at that point, Fellwar Stone can't tap for it.

The relevant rule (important part bolded for emphasis):

106.7 Some abilities produce mana based on the type of mana another permanent or permanents “could produce.” The type of mana a permanent could produce at any time includes any type of mana that an ability of that permanent would produce if the ability were to resolve at that time, taking into account any applicable replacement effects in any possible order. Ignore whether any costs of the ability could or could not be paid. If that permanent wouldn’t produce any mana under these conditions, or no type of mana can be defined this way, there’s no type of mana it could produce.

I mention Sidisi, Undead Vizier in my notable exclusions like you said it's a good fit if you don't have Demonic/Vampiric.

I'm not running Mana Confluence simply because I haven't felt like spending $10 on it. it would definitely be a good call.

I opted for Plaguecrafter over Vindictive Lich, but either or both are certainly fine to use.

For similar reasons as you mentioned I didn't bother with Disciple of Bolas plus, between various other card draw sources I haven't really needed him. Necropotence etc... plus at CMC4 he is competing with a lot of other cards.

Haste isn't super important for me since i've tried to build in a lot of ways to get counters outside of combat, but i think it would fit well if you were running more of a battle cruiser value deck.

Threaten and etc... is a popular way to build marchesa and definitely has a good support structure. I opted to go a different route though and as you can see i went a lot more aristocrats based. a low power big fatties battle cruiser meta will probably find a lot of success with an Act of Treason focused list though.

also, the Zealous Conscripts Infernal Tribute idea is a good one. nice catch.

let me know if you want any feedback on other cards, I've tested or considered cards in most sets that are released.
