Manaform Hellkite's triggered ability looks at the mana that was actually spent to cast the spell, which may be different than the mana cost of that spell. For example, if you cast a noncreature spell without paying its mana cost, this ability creates a 0/0 Dragon Illusion token. In most cases, such a creature would immediately be put into your graveyard.
