H:
Blood Crypt,
Shrieking Affliction,
Drainpipe Vermin,
Mugging
3. square_two:
Breeding Pool,
Wasteland Viper,
Rapid Hybridization,
Serene Remembrance
My intuition says I lose these, but I don't know what the math says.
If I am on the Play:
H: Crypt, untapped [H=18], Vermin. (Affliction does nothing here.)
S2: Pool, lets say Untapped [S2=18], the only card that does anything is Viper.
H: Mugging on Viper, attack for 1, [S2=17].
S2: Remembrance, shuffling Remembrance and Viper. Library order: Remembrance on top and Viper on bottom.
H: Attack for 1, play Affliction. [S2=16]
S2: Only RH in hand, so take 3 from Affliction [S2=13], pass. Hand is now RH, Remembrance.
H: Attack for 1 [S2=12]
S2: No Affliction damage, Draw Viper, play Viper.
H: If I attack and S2 blocks, I can trigger Vermin. If S2 discards Remembrance, I don't think Hybridiazation on the Viper can win the race, since S2 will be at 9 on the next turn, the 3/3 won't be able to attack until the following turn and I am at 18 then to 6. So, the discard, if it happens must be Hybridization. That would delay a 3/3 by another two turns, which I don't think gets there. So, it would seem that it's best to not block at all. So, [S2=11].
S2: Hybridize the Viper, pass.
H: I definitely want to attack here, since Remembrance is the only card in hand. Again, S2 can't race here with just a 3/3 losing Remembrance, so, no block. [S2=10].
S2: Only one card in hand, Remembrance, so [S2=7]. Cast Remembrance, order is Remembrance, RH, Viper. You have a 6 turn clock (18/3) but I have 3 coming next turn, (4), plus 3 on the following turn, plus a potential attack (7). So, attacking does not seem to win yet, so pass.
H: No attack since it can be blocked.
S2: No cards in hand, so Affliction [S2=4], one card in hand, Remembrance, does nothing, so pass, the attack still can't race.
H: Attack, since I can trigger Vermin for gain on a block. If no block, I win the the following upkeep. If blocked, I trigger Vermin, discarding Remembrance, then there is no way for S2 to race the Affliction.
So, I think I win on the Play. Unsure about the Draw, but my guess is that it doesn't make that much of a difference?
More analysis needed, clearly.
