Knight of Old Benalia — Modern Horizons #17

Suspend 5— (Rather than cast this card from your hand, you may pay and exile it with five time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost. It has haste.)

When this creature enters, other creatures you control get +1/+1 until end of turn.
