When you planeswalk to Amy's Home and at the beginning of your upkeep, you may exile a nonland card from your hand with a number of time counters on it equal to its mana value. If it doesn't have suspend, it gains suspend.

: When chaos ensues, time travel. (For each suspended card you won and each permanent you control with a time counter on it, you may add or remove a time counter.)
