702.61a Suspend is a keyword that represents three abilities. The first is a static ability that
functions while the card with suspend is in a player’s hand. The second and third are triggered
abilities that function in the exile zone. “Suspend N—[cost]” means “If you could begin to cast
this card by putting it onto the stack from your hand, you may pay [cost] and exile it with N
time counters on it. This action doesn’t use the stack,” and “At the beginning of your upkeep, if
this card is suspended, remove a time counter from it,” and “When the last time counter is
removed from this card, if it’s exiled, play it without paying its mana cost if able. If you can’t, it
remains exiled. If you cast a creature spell this way, it gains haste until you lose control of the
spell or the permanent it becomes.”
