When Sinister Concierge dies, you may exile it and put three time counters on it. If you do, exile up to one target creature and put three time counters on it. Each card exiled this way that doesn't have suspend gains suspend (Rather than cast this card from your hand, pay its suspend cost and exile it with time counter(s) on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. If it's a creature, it has haste.).
