{t}: Look at the top two cards of your opponent's
deck and put them back in any order.
{u}{r}, target opponent reveals a card from their
hand to you that has not been revealed this way
this turn: if it is a land, gain one mana of that
color. If it is a permanent, this card gains +1/+1
until end of turn. If it is an instant, you may
draw one card. If it is a sorcery you may deal
one damage to target player.
