Knight of Old Benalia

If the spell requires any targets, those targets are chosen when the spell is finally cast, not when it's exiled.

A creature cast using suspend will enter the battlefield with haste. It will have haste until another player gains control of it. (In some rare cases, another player may gain control of the creature spell itself. If this happens, the creature won't enter the battlefield with haste.)

If the card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

Suspend is a keyword that represents three abilities. The first is a static ability that allows you to exile the card from your hand with the specified number of time counters (the number before the dash) on it by paying its suspend cost (listed after the dash). The second is a triggered ability that removes a time counter from the suspended card at the beginning of each of your upkeeps. The third is a triggered ability that gives you the option to cast the card when the last time counter is removed.

If the second triggered ability is countered, the card can't be cast. It remains exiled with no time counters on it, and it's no longer suspended.

You can exile a card in your hand using suspend any time you could cast that card. Consider its card type, any effects that modify when you could cast it (such as flash) and any other effects that stop you from casting it (such as from Meddling Mage's ability) to determine if and when you can do this. Whether you could actually complete all steps in casting the card is irrelevant. For example, you can exile a card with suspend that has no mana cost or that requires a target even if no legal targets are available at that time.

The mana value of a spell cast without paying its mana cost is determined by its mana cost, even though that cost wasn't paid.

Exiling a card with suspend isn't casting that card. This action doesn't use the stack and can't be responded to.

If an effect refers to a "suspended card," that means a card that (1) has suspend, (2) is in exile, and (3) has one or more time counters on it.

Cards exiled with suspend are exiled face up.

The last ability of Knight of Old Benalia affects only creatures you control at the time it resolves. Creatures you begin to control later in the turn won't get +1/+1.
