Aprad, the Soul Wielder

All constructs you control cannot be countered.
Deactivate- When a construct you control would be targeted by a spell or ability, you may pay {w}{u}{b} and look at the top three cards of your library. Choose a card and exile it. You can cast the exiled card without paying its mana costs at
any time. If you cast it during combat, that player cannot cast spells for the rest of the turn.
