Kindle the Inner Flame

"Flashback [cost]" means "You may cast this card from your graveyard by paying [cost] rather than paying its mana cost" and "If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack."

A spell cast using flashback will always be exiled afterward, whether it resolves, is countered, or leaves the stack in some other way.

Any enters abilities of the copied creature will trigger when the token enters. Any "as [this creature] enters" or "[this creature] enters with" abilities of the copied creature will also work.

If a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.

If the copied creature has in its mana cost, X is 0.

If the copied creature is a token, the token that's created copies the original characteristics of that token as stated by the effect that created that token, with the listed exceptions.

If the copied creature is copying something else, then the token enters as whatever that creature copied, with the listed exceptions.

The token created by Kindle the Inner Flame copies exactly what was printed on the original creature and nothing else, with the listed exceptions (unless that creature is copying something else or is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

To behold three Elementals, you can reveal three Elemental cards from your hand, choose three Elementals you control on the battlefield, or reveal and choose any combination that adds up to three. You can't behold the same object more than once to pay this cost.

You must still follow any timing restrictions and permissions, including those based on the card's type. For instance, you can cast a sorcery using flashback only when you could normally cast a sorcery.
