Suspend 10-{R}
(Rather than cast this card from your hand, you may pay {R} and exile it with ten time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
Sacrifice an artifact, creature, or land: Remove a time counter from Greater Gargadon. Activate this ability only if Greater Gargadon is suspended.
