Ekko, Shatterer of Time

Flying
{x}{g}{w}{u}, {t}: Counter X spells and abilities. If a spell is countered this way, exile it with 4 time counters on it instead of putting it in the owner's graveyard. If a spell put into exile this way does not have suspend, it gains suspend. This ability has split second.
Whenever a spell is cast as a result of removing a time counter, untap lands equal to that spell's mana value, and spells in your hand gain flash until that spell resolves.
