Yeah, now that I already have upped my IGT and Voodoo, I really know it would probably be a good match up.
Deja Vu, Gargoyle, Werewolf and Cockatrice can also be used here.
I have searched all elements looking for creatures. Rejected these:
Deja Vu: attack too low. I was even thinking about remove Mercenary.
Gargoyle: costs 5, prefered creatures with cost 4 or less, so they can be played with 2 SNs.
Werewolf: mark is not entropy. They were in 1st version I tested, but would be a shame if he plays werewolf over SN, and then his deck is delayed, maybe for 2-3 turns, while he gets more Entropy.
Cockatrice: the deck is already heavy in life quanta, at least in the start. Frogs cost less and have same attack (although they are more vulnerable).
