Knight of Old Benalia [Modern Horizons]

Suspend 5—{W} (Rather than cast this card from your hand, you may pay {W} and exile it with five 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.) When Knight of Old Benalia enters the battlefield, other creatures you control get +1/+1 until end of turn.
