As the name suggests, this deck's main cards are Mitosis and Devourers. This is my second Quanta Denial deck should be used against Level 3 Ai and any non-Devourer deck.

Play your pendulums, followed by Devourers. Use Mitosis on them and drain your opponent's quanta dry. Play Emphatic Bonds to keep yourself alive and Steal dangerous permanents. Towards the middle of the game, when your Darkness Quanta reaches 75, play Black Dragons and use Mitosis on them and watch them finish your opponent. Oh yeah, and use Heals at the end of the game to get Elemental Mastery!
