Bond With the Unreal

Whenever you second guess, you may reveal
a card from your hand. If you do, you gain
life equal to that card's converted mana cost.
{3}{w}: Second Guess. (Exile two cards from
your hand face down, then exile the top two
cards of your library face down. Look at the exiled cards and put two of them in your hand
and the rest in your graveyard.)
