Must be Special Summoned with "Mask Change" and cannot be Special Summoned by other ways. If this card is Special Summoned: You can target 1 face-up monster your opponent controls; its ATK becomes half its current ATK. Once per turn, during either player's turn: You can pay 500 LP, then target 1 Spell/Trap Card your opponent controls; return it to the hand.
Possible, but also doubtful. 1. The card is not OP, so there's no reason to for it to remain at one. 2. The card isn't strictly necessary for any specific builds and is rarely ever used in mask change hero decks anyway, so there isn't any dire need for them to make multiple copies available.
To be fair, the only reason nobody (not even in real life) ever used this card (or Masked Hero Divine Wind), is because nobody wants to play Avian.
Now that Stratos is released, HERO players in real life can now add Blast or Divine Wind into their list of options, but since Stratos is not available yet for players in DL, Blast will likely remain irrelevant for a long time.
