I've searched the forums for an answer to this question but found multiple contradictive answers and i'd like to have a definitive answer.
Does animar, soul of elements's cost reduction apply to creatures cast using the bestow alternate casting cost, like hypnotic siren for exemple? Is the creature an aura and not a creature anymore before applying cost reduction as part of casting the spell?
If you choose to cast a spell for its bestow cost, it will be an Aura on the stack and Animar's cost reduction will not apply.
A spell with bestow is either a creature or an Aura on the stack. It is never both. Since paying the costs for a spell and determining the cost after additions and reductions happen after the spell is on the stack, Animar's cost reduction effect will not apply to a bestowed card as it will be an aura at the time.
