A few notes: Cards below ~50% presence are true flex slots, so lists vary significantly. Spell Pierce, Get Out, and Roaring Furnace appear in both main and side, meaning players split them differently. Eddymurk Crab at 68% is the biggest flex creature. The core of the deck (Slickshot, Talent, both cantrips, Burst Lightning, Flow State, and the 4-land dual package) is essentially universal.
