Infiltrator il-Kor [Time Spiral Remastered]

Shadow (This creature can block or be blocked by only creatures with shadow.)
Suspend 2{1}{U} (Rather than cast this card from your hand, you may pay {1}{U} and exile it with two time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
