Sfera e Trini agiscono quando si GIOCA una magia.
Unearth non fa giocare - fa rimettere in gioco dal cimitero.
From the Comprehensive Rules: ha scritto:
502.84. Unearth
502.84a Unearth is an activated ability that functions while the card is in a graveyard. "Unearth [cost]" means "[Cost]: Return this card from your graveyard to play. It gains haste. Remove it from the game at end of turn. If it would leave play, remove it from the game instead of putting it anywhere else. Play this ability only any time you could play a sorcery."
Suspend invece funziona così:
From the Comprehensive Rules: ha scritto:
502.59. Suspend
502.59a Suspend is a keyword that represents three abilities. The first is a static ability that functions while the card with suspend is in a player's hand. The second and third are triggered abilities that function in the removed-from-the-game zone. "Suspend N--[cost]" means "If you could play this card from your hand, you may pay [cost] and remove it from the game with N time counters on it. This action doesn't use the stack," and "At the beginning of your upkeep, if this card is suspended, remove a time counter from it," and "When the last time counter is removed from this card, if it's removed from the game, play it without paying its mana cost if able. If you can't, it remains removed from the game. If you play it this way and it's a creature, it gains haste until you lose control of it."
502.59b A card is "suspended" if it's in the removed-from-the-game zone, has suspend, and has a time counter on it.
502.59c Playing a spell as an effect of its suspend ability follows the rules for paying alternative costs in rules 409.1b and 409.1f-h.
Quindi semplicemente sospendi la magia pagando il suo costo di suspend [e nulla più, ancora non la stai *giocando*], e quando togli l'ultimo segnalino puoi *giocarla* senza pagarne il costo di mana, ma pagando ovviamente qualsivoglia costo addizionale indotto da sfere varie.
