Trample, Haste
If Kiba would be destroyed from any source of
combat or noncombat damage, Regenerate and
put a -1/-1 counter on Kiba.
Kiba gains +2/+0 for each -1/-1 counter on him.
Kiba takes X less damage from any source of
damage, where X equals the number of -1/-1
counters on Kiba.
{t}: Remove up to two -1/-1 counters from
Kiba. You may only activate this ability as a
sorcery.
