I don't think that's a problem, considering Wizards was willing to print this card:
Heroes Remembered {6WWW} |Sorcery| You gain 20 life. / Suspend 10--W (Rather than play this card from your hand, you may pay W and remove it from the game with ten time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, play it without paying its mana cost.)
Also, why the extra "Gain 2 life"? Makes it look less clean.
