Inevitable Betrayal

If the first triggered ability of suspend (the one that removes time counters) is countered, no time counter is removed. The ability will trigger again at the beginning of the card's owner's next upkeep.

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

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

If you cast a card "without paying its mana cost," such as with suspend, you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those if you want to cast the card.

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.

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.

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.

A card with no mana cost can't be cast normally; you'll need a way to cast it for an alternative cost or without paying its mana cost, such as by suspending it.

If a card with no mana cost is given an alternative cost equal to its mana cost (by Snapcaster Mage, for example), that cost cannot be paid and the card cannot be cast this way.

Cards exiled with suspend are exiled face up.

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.

When the last time counter is removed, the second triggered ability of suspend (the one that lets you cast the card) triggers. It doesn't matter why the last time counter was removed or what effect removed it.

You may fail to find a creature card in your opponent's library. This may be because they don't have any creature cards, or it may be because you simply don't like any of the creature cards they do have.
