No Counters?

(No Counters? is blue.)
Cast this card at the end of your turn, only if you casted a spell this turn.
If a spell you casted was not countered this turn,
put this card into the graveyard with a No
Counters counter on it. If a spell you control
would be countered, remove a No Counters
counter from this card and counter that spell,
then exile this card from the graveyard.
