How is bonus damage from Blaze affected by effects that allow the same spell to be cast multiple times?

When Blaze is cast (Cast: deal 2 damage. Deal 1 additional damage for each other time you have cast Blaze this turn AND for each other Blaze you currently have prepped.), you deal 1 additional damage for each other time you have cast Blaze this turn. Designer's intent is that those other casts do not need to have been a different copy of the card.

Example: Jian has one copy of Blaze prepped to Breach I and uses Black Mirror to cast it. The first cast of Blaze will deal 2 damage (2 base damage, no other casts this turn, no other copies of Blaze prepped). The second cast of Blaze will deal 3 damage (2 base damage, 1 damage for the prior cast of the spell, no other copies of Blaze prepped).

Example: Kadir has one copy of Blaze prepped to Breach I and casts it during her casting phase, dealing 2 damage. During her main phase, she uses Otherworldly Gate to recover and prep the same copy of Blaze. Using a relic, she casts Blaze during her main phase. The second cast of Blaze will deal 3 damage (2 base damage, 1 damage for the prior cast of the spell).
