Awakening of Cthulhu

Destroy up to two target creatures. If those
creatures converted mana cost is 6 or more, you
may take a card from outside of the game and put it onto the battlefield tapped. If that creature's
ability triggered once, do it twice instead. If that creature costs five or more mana, that creature
gains trample and lifelink. If that creature costs
four or less mana, put a +1/+1 counter
on that creature.
What the hell is that?
