Atomic Microsizer

Most Equipment buys durability: a permanent statline welded to a body, paying its cost once and cashing in every combat. This one inverts the logic. The +1/+0 is almost incidental; the real payload is the attack trigger, which reaches across the board to shrink a chosen creature to a base 1/1 for the turn and, if that creature is one of yours, wave it past blockers. The "up to one" clause is where the flexibility lives, because the trigger fires only when the equipped creature attacks and only reads the board during your own combat. Point it at a fellow attacker and you hand it evasion; the size reset costs you nothing when the target was already a small body slipping through for chip damage. Point it at an opposing blocker and you have collapsed a fearsome 6/6 into something a token can trade with; note the unblockable clause only ever applies to attackers, so the shrunken defender can still declare a block, and the value you extract is the size reduction, not its removal from the fight. Everything resets at end of turn, so this disrupts a single combat rather than answering a threat for good. It belongs to the small class of blue Equipment built to manipulate combat directly rather than protect a carrier, closer to a repeatable trick than a weapon, and asked to earn its keep one swing at a time.
