Rulings
For split cards, the flashback cost you pay is determined by the half you cast.
Only instant and sorcery cards in your graveyard when Backdraft Hellkite’s triggered ability resolves will gain flashback. Instant and sorcery cards that are put into your graveyard later in the turn won’t gain flashback.
Once Backdraft Hellkite has attacked, its ability will resolve and grant the appropriate cards flashback even if Backdraft Hellkite leaves the battlefield before the ability resolves or after it resolves but before you cast the spells.
If you cast an instant or sorcery with 
in its mana cost this way, you still choose the value of X as part of casting the spell and pay that cost.
If an instant or sorcery card in your graveyard already has flashback, you may use either flashback ability to cast it from your graveyard.
You may pay any optional additional costs the spell has, such as kicker costs. You must pay any mandatory additional costs the spell has, such as that of Momentous Fall.
