The Curator

The Curator's power and toughness are each
equal to the number of unique creature types
among creatures you control.
{10}, {t}: Exile target creature. Create a token that's
a copy of the exiled card, except it is a 3/3 Mimic artifact in addition to its other types. This ability
costs {1} less to activate for each unique creature
type among creatures you control.
It's made it its sole purpose to collect all life.
