Time counter

Time counters are counters that are usually removed during the upkeep step. If the last time counter on a card is removed, an effect will occur.

Mechanics
Two mechanics use time counter both were introduced during the Time Spiral block.
 * Vanishing
 * Suspend

Before Time Spiral
Before Time Spiral, only three cards used time counters.
 * Tourach's Gate from Fallen Empires is the first enchantment aura to use time counters.
 * Infinite Hourglass and Time Bomb from Ice Age are the first artifacts to use time counters.

Time counter interaction
There are a few cards that can interact specifically with time counters.
 * Jhoira's Timebug puts a time counter on or removes a time counter from a permanent you control or a suspended card you own.
 * Fury Charm removes two time counters from a permanent or suspended card.
 * Timebender puts two time counters on or removes two time counters from a permanent with a time counter on it or a suspended card.
 * Timecrafting puts X time counters on or removes X time counters from a permanent with a time counter on it or a suspended card.
 * Dust of Moments puts two time counters on or removes two time counters from each permanent with a time counter on it and each suspended card.
 * Rift Elemental</c> removes two time counters from a permanent you control or a suspended card you own.
 * Shivan Sand-Mage</c> puts two time counters on or removes two time counters from a permanent with a time counter on it or a suspended card.


 * As Foretold</c> from Amonkhet allows a player to pay 0 rather than pay the mana cost for a spell they cast with converted mana cost X or less, where X is the number of time counters on As Foretold.

Additionally, any card that interacts with counters in general may affect permanents with time counters, such as Doubling Season</c>, Price of Betrayal</c>, Vorel of the Hull Clade</c>, and cards with Proliferate. Such cards cannot affect time counters on suspended spells since those spells are in exile.
