Balrog, Disgraced Champion

At the beginning of your end step, if Balrog,
Disgraced Champion is not tapped, put a
fury counter on it.
When Balrog, Disgraced Champion attacks,
remove all fury counters from it. For each fury
counter removed this way, defending player may
discard a card. If they don't, it gains +2/+0 and
Menace until end of turn.
