Runic Supression

Creature attacking you or planeswalkers you control don't cause abilities your opponents control to trigger. Those creatures lose up to 1 of their abilities of your choice until end of turn.
When an attacking creature deals damage to you, put a -1/-1 counter on that creature.
{3}{w}{w}: Until end of turn, creatures you control gain +1/+1 and all other creatures get -1/-1.
