Firefright Mage

The exception clause carries more design weight than it looks: most evasion-granting effects simply turn off blocking, but this one carves out artifact creatures and red creatures specifically, reading less like a gift to the controller than a statement about what red is allowed to bend. Red can shove a creature past almost anyone, but not past its own kind and not past cold metal. As a Spellshaper, it converts a discarded card and a tap into the effect at instant speed, repeatable turn after turn so long as the hand holds fuel, which is the structural trade that defines the class: a creature body standing in for a spell you keep recasting at the cost of grip. The body is fragile and the discard is real, so the engine asks you to value a fistful of dead cards more highly than the blockers it slips past value their lives. What balances it against a one-shot unblockable spell is the delay: the plus a card means every activation has to justify itself, and a Spellshaper drains the hand it depends on. It belongs to the line of red Goblins built to turn a stalled board into a clock, useful precisely when the cards left in hand are worth less than the damage they can buy.
