If a cost associated with a special action, such as a suspend cost or a morph cost, has an {X} or an X in it, the value of X is chosen by the player taking the special action immediately before they pay that cost.
A player who has a card with suspend in their hand may exile that card. This is a special action. A player can take this action any time they have priority, but only if they could begin to cast that card by putting it onto the stack. See rule 702.62, “Suspend.”
A player who has a card with foretell in their hand may pay {2} and exile that card face down. This is a special action. A player may take this action any time they have priority during their turn. See rule 702.143, “Foretell.”
After resolving a madness triggered ability (see rule 702.35), if the exiled card wasn’t cast and was moved to a public zone, effects referencing the discarded card can find that object.

Suspend
To time travel means to choose any number of permanents you control with one or more time counters on them and/or suspended cards you own in exile with one or more time counters on them and, for each of those objects, put a time counter on it or remove a time counter from it. See rule 702.62, “Suspend.”
Madness
Rulings
If you copy a "Mastery" spell and the alternative cost was paid, the copy will resolve as though the cost was paid.
The mana value of a spell on the stack is determined by its mana cost, not any alternative costs you used to pay for it.
In a multiplayer game, you choose which opponent takes the prescribed action as the spell resolves.
If you choose to pay one alternative cost, you can't pay any other alternative costs. For example, if an effect lets you cast a "Mastery" spell "without paying its mana cost," you can't also choose to pay its given alternative cost.
If an effect increases or decreases the cost of spells you cast, that cost increase or decrease is applied to the alternative cost you chose to pay. In that case, the cost was still paid for the purposes of the effect, even if you paid more or less for it when it was cast.
