Fangkeeper's Familiar

Flash on a modal enters trigger is the wrinkle, and it rearranges the sequence in a way most Sultai flex cards never do. This is not a charm you aim in three directions at the moment of casting: the mode is chosen only after the 3/3 body has already resolved onto the battlefield, when the enters trigger goes onto the stack. That one step of delay is the tension. You commit the creature at instant speed, then read the board and pick your answer: a hard counter for a creature spell, enchantment removal, or a life-gain-and-surveil mode that feeds delve, reanimation, or simply keeps you upright. The opponent has to respect all three from the moment you leave mana open, since the flashed body threatens to arrive at end of step wearing whichever hat the game demands. The limits are honest ones, and they define the card as much as the flexibility does. The counter clause stops creature spells only, so the burn or removal actually killing you passes through untouched, and the destroy mode reads enchantments, leaving an artifact-heavy board answered by nothing but a small snake and three life. Miss the reactive window and you have flashed in a 3/3 whose enters trigger cashes out to a modest life-and-dig: a fair floor, not a reason to jam it main-phase. What makes the design cohere is that all three modes genuinely want instant speed, and the four-mana color identity pays for each without stapling on effects that do not belong.
