Oric, Samite Sovereign

If a source would deal damage to you or another
permanent you control, you may tap an
untapped creature you control. When you do,
prevent X of that damage, where X is that
creature's toughness. Sacrifice that creature at
the beginning of the next end step.
Whenever a spell or ability you control prevents
one or more damage to you or a permanent you
control, you may draw a card.
