In the Mulligan you need to draw fast the first turns to get your combo pieces.
Exodia Combo seems a bit hard to setup but with all the burn damage and board control tools you don’t need to fireball for free mana. Just try to copy with Potion of Illusion at least 2 Sor.Apr. in 1 turn and 1 Tony with the other Potion. If you fireball for 1 mana should be OK. You have enough draw and freeze tools to stale the game.
