Nascent Megamorph

Nascent Megamorph enters the battlefield with
two counters of your choice on it from among
Trample, Haste, Menace, Shield and +1/+1.
Whenever Nascent Megamorph attacks, target
opponent reveals cards from the top of their
library until they reveal a creature card. Until
end of turn, you may have Nascent Megamorph
become a copy of that creature. Shuffle all cards
revealed this way back into their owner's
library.
