Martin Hatch, Time's Door

Flash, ward {4}
Whenever a creature enters from exile, draw 1.
{x}: Exile target creature with X power and put
2 time counters on it. If it doesn't have suspend,
it gains suspend. (At the beginning of its owner's upkeep, they remove a time counter. When the last
is removed, they may play it without paying its
mana cost. If it's a creature, it has haste.)
