Gearfried, the Collector

Eminence —Nonland permanents you control
are artifacts in addition to their other types.
Affinity for artifacts
{t}: Target nonland permanent you don't control becomes an artifact in addition to its other types
until end of turn.
Whenever an opponent activates an ability of an
artifact, create a copy of it. If you already control
a permanent with that name, gain control of it
until the end of your next turn instead.
