Mulligans
This deck aims to set up a OTK using Dreampetal Florist, Malygos, and a combination of Prince Taldaram/Flobbidinous Floop/Ixlid, Fungal Lord.
Turns 1-6: The goal here is to ramp, draw cards, and defend if necessary with Biology Project, Wild Growth, Nourish, Ferocious Howl, Branching Paths, Juicy Psychmelon, Lesser Jasper Spellstone, Naturalize, Swipe, Spreading Plague, Malfurion the Pestilent, Ultimate Infestation, and Arcane Tyrant . Try to save a Biology Project and a Swipe.
Turn 7+: Play Dreampetal Florist. Ideally, you want the cost reduction to hit Malygos to guarantee spell damage +20 (Plan A). You will only get spell damage +15 with the others (Plan B).
Plan A: Play Ixlid, Fungal Lord, Malygos, and Prince Taldaram. This will leave you with spell damage +20 and leave you with 0 mana. Use 2 x Moonfire for 42 damage.
Plan B: Play Malygos on the first turn. Next turn, play Flobbidinous Floop, Ixlid, Fungal Lord, and Prince Taldaram. This will leave you with spell damage +15 and either 1-3 mana left. Use 2 x Moonfire for 32 damage. Use any remaining Biology Project and Innervate to play Swipe for an additional 19 damage.
