Depth Of Cunning

Bound: {1}{u}{u} (You MUST cast this spell for its
Bound cost, unless you control a legendary creature or
planeswalker. If you do, change this spell's text by
replacing all instances of "For the rest of the game"
with "Untill the end of turn.")
For the rest of the game, whenever a creature
you control attacks, tap all permanents defending player controls. Creatures tapped this way don't
untap during their controller's next untap step.
