Edgar, King of Figaro
The interesting half of this card is the keyword nobody in Magic had ever needed before it. Coin flips have lived in Magic's fringe since the earliest sets, a variance mechanic red tolerated and blue never touched: Krark's Thumb let you flip twice and choose, Fiery Gambit dared you to keep calling it. The Two-Headed Coin does something different in kind. It does not improve your odds; it deletes them, converting the first flip of every turn into a guaranteed win rather than a fifty-fifty. That turns a class of gimmick cards built around the gamble into deterministic engines, which is a strange thing to hand to blue, historically the color that hates leaving anything to chance and would rather counter the spell than roll for it. The enters trigger is the more conventional payoff, rewarding an artifact-dense board with a burst of cards, and it points the build toward the same place the coin keyword does: a deck stuffed with artifacts and with the handful of flip cards that suddenly read as pure upside. The tension in the design is that these two halves want slightly different shells (one wants raw artifact count, the other wants coin payoffs to abuse), and reconciling them is the deckbuilding problem the card poses. The body, sturdy but not threatening, is content to sit back and let both engines run.
