Flying (This creature can't be blocked except by creatures with flying or reach.) Rankle has lifelink (Damage dealt by the creature also causes its controller to gain that much life.) and haste (This creature can attack, and as soon as it comes under your control.) as long as an opponent controls no creatures. When Rankle enters the battlefield, you may pay 1 life. When you do, each player discards a card and sacrifices a creature. Whenever a player discards a card, Rankle perpetually gets +1/+0.
