Colossus, Cosmic beast

Trample, Ward {4}
Nightmare from beyond — Colossus can't be
blocked except by all creatures defending player controls, and takes half damage rounded up
from nonartifacts.
{2}{u}{b}{g},{t}: Colossus gets two +1/+1 counters
and gains hexproof until end of turn.
It gorges itself on whole worlds.
