Statue Collector

{g}, {t}: Put a +1/+1 counter on Statue Collector.
{1}{u}: Until end of turn, whenever Statue Collector deals combat damage to a creature, that creature becomes an artifact, and it loses all other card types. Then you gain control of it. (This effect lasts indefinitely.)
"In case we become statues, I want to have a
nice pose." - Bob the Wise
