Rulings:

• 8/23/2019 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.
• 8/23/2019 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.
• 8/23/2019 If you cast an instant or sorcery with <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost this way, you still choose the value of X as part of casting the spell and pay that cost.
• 8/23/2019 If an instant or sorcery card in your graveyard already has flashback, you may use either flashback ability to cast it from your graveyard.
• 8/23/2019 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.
• 8/23/2019 For split cards, the flashback cost you pay is determined by the half you cast.
