JingLiu

First Strike, Vigilance, Indestructible
Whenever Jingliu attacks, each creature you
control loses 1 toughness. For each toughness
lost this way, put a +1/+0 on JingLiu until the
end of the turn. If you lost more than 5 life this
way, put a +8/+8 counter on JingLiu and she
gets double strike until end of the turn.
