If you want to be mean you can run Lethal Vapors/Spreading Plague. The god's don't care since they are indestructible but most other decks cry a little.

I don't think anyone has written me such a long comment on a deck of mine, so let me start off by saying thank you!

I'm absolutely unphased by the RR casting costs of Collective Defiance and Reforge the Soul. If my draw engine is working at all (via Mythos/Howling Mine/Waste Not etc), it should be pretty easy to find two red mana sources.

I AM phased by dying before I can get my deck going. If I don't get Waste Not, I'm dead in the water. It is the industrial-grade gorilla glue holding this deck together. I thought about playing around with other ways to generate black mana (Cabal Coffers for example), and additional ways to not die early game (Lethal Vapors for example), but am unsure of how to fix that. I might just go with it and make this a YOLO deck that I play for fun. Vampire Nighthawk is a good idea for surviving the early game, and I might fiddle around with things to include it. The sub gimmick I had with this deck was running as little creature cards as possible, but I might be willing to break that for Nighthawk.

Culling the Weak is something I was thinking of too, so I could actually use the cards I draw and the zombies I create, but it's unreliable if I'm running against a deck that doesn't run many creatures.

I know what you talking about that i need creatures. Im trying to skip them with Spreading Plague, Lethal Vapors,Overburden and all the boardwipe. If i want to make it Creature heavy i could just remove all those cards. Thx for your suggestion. :)

Rhadamanthus on Lethal Vapors weirdness

To post #4 above: Yes, they can't keep responding by adding another block of activations. They have to stop and do something else.

To post #5 above: Yes, this is a loop around the same game state. The game doesn't have a hard official definition for "game state", because it's not just a matter of objects and events in some particular configuration. It's also about what the objects and events mean in a practical sense for the game. You activating Lethal Vapors 10 times and me responding by activating it 10 times produces a result that's indistinguishable from both of us doing nothing, or from both of us going back and forth with responses of 10 activations for the next 5 minutes. None of what we're doing is actually advancing the game state.

No one is required to help your opponent figure out the best strategy for escaping the situation. If they try to go with a slow-play method then they'll get infractions. The penalty is a warning, but repeated slow play infractions are upgradeable to a game loss.

Rhadamanthus, so if I were to activate Lethal Vapors a googol times on my opponent's upkeep, they activate a googol times in response, then I activate another googol times in response, my opponent would be unable to activate Lethal Vapors anymore because as the active player they must make a different choice?

I have Lethal Vapors on the field and Teferi's Protection in hand.

I activate Lethal Vapors a googol times then I pass priority. My opponent then activates Lethal Vapors the same number of times then passes priority back to me. Which one of us has to stop activating Lethal Vapors first?

In a tournament setting, suppose I successfully resolve my googol triggers of Lethal Vapors and my opponent doesn't skip any turns. My opponent has an Emrakul, the Aeons Torn in their deck. They would want to draw their deck, discarding to hand size until they hit Emrakul, then discard Emrakul to hand size and repeat the cycle until I've skipped a googol turns. However, since playing a googol turns is impossible, what would happen?

Would my opponent be forced to stop discarding Emrakul, since each Emrakul discard does not advance the boardstate but instead resets it repeatedly in a way similar to Four Horsemen? Would they be forced to just keep on manually doing the iterations until the round goes to time? Would they be allowed to shortcut and say "I do this draw thing until you take a turn again"?
