Riptide Chronologist

Untapping all creatures of a chosen type sounds like a formality until you remember what untapping buys in combat: pseudo-vigilance across an entire tribe, a fresh wall of blockers after your attackers committed, a surprise swing when the opponent thought your board was tapped out. The chronologist hands a tribal deck a one-shot combat reset, gated behind a self-sacrifice so it can never become a repeatable engine. You cash in the 1/3 Wizard for one decisive turn rather than leaning on it across many. The choose-a-type wording dates the card to an era of tribal scaffolding, when "all your Goblins" or "all your Soldiers" described a meaningful number of bodies rather than one or two stragglers; the effect scales with how committed the deck is to a single creature type. The five-mana investment for a single use is genuinely steep, and the card never found a home outside the tribal context it was drawn for. The design idea underneath is more durable than the rate: a creature that converts a tapped board back into a live one at instant speed, with the sacrifice cost standing in for the balance that a free, recurring untapper would never have. It is a combat trick disguised as a body, payable once, and built to reward a deck that fields a lot of one thing.
