Fight Rigging

Hideaway 5 (When this enchantment enters
the battlefield, look at the top five cards of your library, exile one face down, then put the rest on the bottom in a random order.)
At the beginning of combat on your turn,
put a +1/+1 counter on target creature you
control. Then if you control a creature with
power 7 or greater, you may play the exiled
card without paying its mana cost.
