Ahoj!
1) Gigantomancerova schopnost pouze mění charakteristy zacílené bytosti. Bytost stále zůstává na bojišti a Doom Blade tak neztratí svůj cíl.
Nejsem si jistý, co myslíš větou "Jedná s mi o to jestli se tato schopnost dá použít podobně jako např keyruny". Můžeš to nějak rozvést?
2) Ano, je to tak. Tím, že bytost "projde hřbitovem", ztratí Persist. (Nicméně ten se stále vyhodnotí, protože u "leaves-the-battlefield" triggerů jako je Persist se hra dívá do okamžiku těsně před smrtí a v té chvíli na bytosti ještě Persist byl.)
400.7. An object that moves from one zone to another becomes a new object with no memory of, or relation to, its previous existence. There are seven exceptions to this rule:
400.7a Effects from spells, activated abilities, and triggered abilities that change the characteristics of a permanent spell on the stack continue to apply to the permanent that spell becomes.
400.7b Prevention effects that apply to damage from a permanent spell on the stack continue to apply to damage from the permanent that spell becomes.
400.7c If an ability of a permanent requires information about choices made as that permanent was cast as a spell, including what mana was spent to cast that spell, it uses information about the spell that became that permanent as it resolved.
400.7d Abilities that trigger when an object moves from one zone to another (for example, “When Rancor is put into a graveyard from the battlefield”) can find the new object that it became in the zone it moved to when the ability triggered, if that zone is a public zone.
400.7e Abilities of Auras that trigger when the enchanted permanent leaves the battlefield can find the new object that Aura became in its owner’s graveyard if it was put into that graveyard at the same time the enchanted permanent left the battlefield. It can also find the new object that Aura became in its owner’s graveyard as a result of being put there as a state-based action for not being attached to a permanent. (See rule 704.5n.)
400.7f If an effect grants a nonland card an ability that allows it to be cast, that ability will continue to apply to the new object that card became after it moved to the stack as a result of being cast this way.
400.7g A resolving spell or activated ability can perform actions on an object that moved from one zone to another while that spell was being cast or that ability was being activated, if that object moved to a public zone.
