Black Panther, Most Dangerous (MSC-584) [Commander: Marvel Super Heroes]

Whenever Black Panther is dealt damage, he deals that much damage to any other target.

Power-up — 5WW: Put two +1/+1 counters on Black Panther. Other creatures you control get +2/+2 until end of turn. (Activate each power-up ability only once. Reduce the cost by his mana cost if he entered this turn.)
