Wire Surgeons

Encore is a keyword that normally lives on the card that has it, printed and paid for once. What this artificer does is graft that mechanic onto a whole category retroactively: every artifact creature already in your graveyard gains the ability, priced at its own mana cost, whether or not it was ever designed to be recast. That is the real engine here, and it changes what an artifact-creature graveyard is worth. Robots that died in combat, spent Myr, mana rocks that happen to be creatures: all of them become one-shot swarm payloads, exiled to spit out a token copy per opponent that swings and then vanishes at end step. The body itself is a serviceable evasive threat with Fear, hard to block in a metagame short on black or artifact defenders, but the swing on the card is the recursion clause, not the six-power attacker. The whole thing is sorcery-speed and self-limiting: encore exiles the card, so each dead robot is a single detonation, not a loop. The design asks you to fill a graveyard with expensive artifact creatures worth reanimating for one explosive turn rather than to protect any single threat. It is a build-around wearing a beater's stat line, and the encore-granting text is doing all the structural work.
