Sturmgeist

A body that reads its stats straight off your hand size is an old blue tension made flesh: a creature that pays you for the cards you have not yet spent. That structure pulls against the instinct to empty your hand casting card draw and cheap interaction, since every spell you resolve shrinks the flier on the board. Cast it into a full grip and it lands as a serious threat; play out your turn first and it barely clears a token; cast it as your last card and it enters a 0/0 and dies on the spot to state-based actions. The combat trigger is the elegant part, and the part that makes the whole thing self-correcting. Each hit refills the hand it has been measuring, so a Sturmgeist that connects keeps its own size topped up while drawing into the cards that carry the rest of your game. The risk runs one way and runs sharp: an unanswered one snowballs hand size and clock at once, but a single removal spell deflates the threat instantly, dropping a hand-sized flier to nothing while the cards that were inflating it sit safely in your grip. It rewards holding back without quite forcing it, with no protection and no tricks to lean on, just a clock whose size is a live readout of how full your hand is. The variable flier paid by hand size is a recurring blue silhouette, and this one states it about as plainly as the design comes.
