Disciple's Coronation

Bear witness — Choose a creature type. Sacrifice
all creatures that you control of the chosen type
except one. The remaining creature gets 2 +1/+1 counters for each creature sacrificed this way
and the abilities of the sacrificed creatures.
"I stand before a being with a thousand names. It
whispers one: The Witness. Remember it. Remember
that name."
