Forkbeard on Miirym, Sentinel Wyrm: Double Dragon

Oh this is a lot to process, ha. Here's some thoughts around the suggestions.

  • Genesis Wave - love the card, definitely tempted as another 'sneak into play' option.
  • Equilibrium - also love this card and use it to great effect in my simic elf deck, but I'm not sure that I can justify it in here due to the already hefty casting costs on all these dragons. More on that later...
  • Sylvan Library & Mana Vault - undeniably amazing cards, I just don't have spares laying around just now. Our play group allows proxies but we have specific rules around them; a maximum of 3 nonland proxies per deck and you have to own a real copy of it. I've opted for Doubling Season, Parallel Lives & The Great Henge for those slots. I'm already running Worldly Tutor in here.
  • Shifting Shadow - this is a VERY interesting card, I've never seen it before! I wouldn't play it without Miirym on the table but I do think this card is neat.
  • Mana Echoes - an awesome card and I've used it to great effect in mass token swarm decks + sliver combos, but I'm not convinced it's a great call in a dragon brew. Might be worth trying but I'm not sure what I'd cut for it.
  • Rhythm of the Wild - another beaut of a card and I had it in here, but having played the deck a few times now I absolutely want/need my tokens to have haste as well.
  • Spectacular Showdown - in my experience with the deck so far, win-more stuff like this isn't needed. The dragons _are_ the finishers.

  • Alright so about the hefty casting cost problem of dragons in general. Yeah. Now that I've had a chance to play the deck a bit, I'm running into the same problems I had with Atarka. With so much ramp + treasure support (treasures are particularly rampant in my playgroup), Commander in general is so fast these days and this deck had a very difficult time keeping up. I really like the brew I have here, but I need to consistently ramp to have any hope of getting this battlecruiser off the ground. I need to start thinking about fast mana (Ancient Tomb, Mana Crypt etc) because I'm finding that some games don't go beyond 5 turns these days. Dark times for a Timmy like me.

    I say cut Thundermaw Hellkite too. Idk I feel like having Genesis Wave resolve with x being 7 or greater would be fun. I also want to suggest Equilibrium. Bounce your own creatures could be a good idea.

    Ok but what about Sylvan Library or Worldly Tutor? Or other really powerful cards like Mana Vault

    Hey Cloudius, did you see that they are reprinting Imperial Seal in Double Masters 2? There are also rumors about reprinting Capture of Jingzhou. I immediately had to think of your deck:) Btw, I had written before the I was trying for a less strong version of your deck. But it doesn't work. Once they know what the game plan is you immediately become archenemy. Well, they are reprinting Mana Vault, too, and Cavern of Souls. And I'm hoping for Mana Drain

    • Sol Ring
    • Goblin Engineer (It does not really synergize with the combo, it was in to find Zuran Orb but I kind of have enough ways to find it and not enough artifacts to sacrifice.)
    • Roil Elemental (It was a cute card but I had to cut one more card for some more consistency and with the amount of tutors I play generally I will always rather have Tatyova or Gitrog Monster which are both tutorable by Bring to Light.)
    • Pact of Negation (Pact of Negation is kind of an expensive card and I think I like Pyroblast more, it's mainly to combat counterspells on the second sunrise anyway and Pyroblast has some added utility to it which I think makes it better.)
    • Mana Vault
    • Overgrown Tomb (Decided I want to run just 3 shock lands, this one might get back into the deck but I opted for others first.)
    • Mox Diamond
    • Mana Crypt
    • Krark-Clan Ironworks (Decided to get rid of the KCI saccing mana rocks before second sunrise plan, it was too convoluted and I want to go for a more land centric deck.)
    • Valakut Exploration (This was also one of my other win conditions, and I liked Roil Elemental first above this but decided to cut both.)
    • Izzet Chronarch (Got replaced by Timeless Witness.)


    • Krosan Wayfarer (Has some early game utility while still being excellend in the Combo.)
    • Pyroblast
    • Cosmic Intervention (I somehow overlooked this card but I am really excited to add this as an early game play for value.)
    • Uro, Titan of Nature's Wrath (Uro is already an insane card, it sacrifices itself which is great, it's basically a recurrable Explore with the added bonus of sometimes being a powerful body, I think it will work excellend in the deck.)
    • Farseek
    • Explore (Both replace my mana rocks for some early mana ramp.)
    • Breeding Pool
    • Temple Garden
    • Hallowed Fountain
    • Timeless Witness
    • Unbridled Growth (Fixes mana and sacrifices for a card, the other candidate was chromatic star which would also be good but I think Unbridled will have more value as you don't need to sacrifice it to gain it's fixing effect.)

    I decided to cut my mana rocks that don't provide a color except for when they have a way to sacrifice themself which also made me cut my KCI from the deck.

    Other Ideas: + Valakut, the Molten Pinnacle + Vesuva + Prismatic Omen

    Quickspell on Does Hullbreaker Horror combo with …

    1 month ago

    I am confused. I've seen a lot of combo descriptions on Hullbreaker Horror + Sol Ring + some 0 mana card like Everflowing Chalice.

    Do you even need a third card? Doesn't this work:

    1. Have Hullbreaker Horror (HH) on the bf.

    2. Cast Sol Ring (SR). HH trigger goes on to the stack, chosing to take SR back to hand.

    3. Before HH trigger resolves, tap SR to float two colorless mana. HH trigger resolves and SR returns to hand.

    4. Use one of the two colorless mana to cast SR > repeat to float infinite colorless mana.

    The same should work with Mana Crypt, Mana Vault or Grim Monolith.

    Everflowing Chalice is just a way to store that mana, isn't that correct?

    Regarding your update

    Cemetery Prowler - Is it's primary purpose GY hate, early blocker, ramp? I feel GY hate is what you were going for. Why not add a Soul-Guide Lantern in it's place or even a Scavenging Ooze. This way you are reactive rather than reliant on attack. Something to consider regarding creature count and pump draw spells. But personally, I feel you are light on beaters. I know your deck is a big more aggressive so perhaps thats just how it plays. I think Kogla, the Titan Ape in your maybeboard would be helpful. Synergy with eternal witness, provides creature and artifact/enchantment removal. Unlike bane of progress, won't remove your land enchantments

    Budget per card? - I added mana crypt to Xenagos and went ham depending on how much of a threat I was viewed as. If not crypt then perhaps Mana Vault might be worth considering in place of time of need? Unless you are actively trying to assemble creature based infinite combat rather than passively drawing into them, ramp might be a higher priority for T2 Xenagos. Having additional ramp redundancy for Xenagos is nice. The untap cost is steep, but depending on your opening hand. or if you just need a little more juice for a draw spell, or to cast your hand after a wheel, it could be useful.

    The cards that I would buy for this deck if they weren't too expensive would be mana rocks, probably Grim Monolith , Mana Vault & Mana Crypt. I have all the Eldrazi and tribal synergies I can play in this deck.
