A Moment of Clarity

Ward - Put an organ counter on target creature you control. (creatures with organ counters on them get
"at the beginning you your upkeep, sacrifice this card unless you pay {1} for each organ counter on it")

Whenever you put a counter on a permanent, target creature gets -X/-X until the end of the turn
where X is the number of counters on it. This
ability triggers only once each turn.
