Mulligans
Another Togwaggle theorycraft, featuring Arcane Tyrant. This deck sacrifices some armor by omission of 2xFerocious Howl and 1xBranching Paths in order to run 2xUltimate Infestation, which naturally wants 2xArcane Tyrant.
Running 2xBiology Project guarantees we can rely on Nourish for card draw if we do not hit Ultimate Infestation early. Against aggro, Biology Project should not punish this deck too hard, as aggro will exhaust their hand with the additional mana before finding lethal. Against control/combo, you should be able to out-draw your opponent and find the Togwaggle combo, disrupting their gameplan before they capitalize on Biology Project.
Only 1xDreampetal Florist and 1xJuicy Psychmelon should be necessary to pull the combo pieces together with the card draw available in this deck.
