Zhalfirin Stabilizer

{2}, Exile a nonland card from your hand: Put
four time counters on the exiled card.
If it doesn't have suspend, it gains suspend.
{4}, Sacrifice Zalfirin Stabilizer: Until your
next turn, players can cast spells only during
their own turn.
Slowly but surely, Zhalfirin mages managed to get a
slight touch of the outside world. And sometimes also
let their presence to be felt.
