Probably the Fastest PVP fire mono deck
Except for the fact that it's not mono-Fire. It uses Aether creatures
Both your deck and the deck in your linked thread are both very fast, but none of them are the fastest PvP deck. Yours is very nice but it can be easily made faster by replacing the cards that do not do damage (Deflagrations, Fire Storms) with damage cards (Hammers, Giant Frogs, Ruby Dragons).
a big and bloated rainbow decks have not even theoretical chance to win
This isn't true, either. Big and bloated rainbow decks DO have a theoretical chance to win, especially if your Cremations are the last 6 cards in your deck.
