@Severity1993 Regarding AF, besides activating Belial on turn 8 and then enduring, you can also gain an advantage by getting Sandalphon through before receiving a 10-cost artifact. Give it a try!
@Severity1993 I understand your frustration with Luria reducing your healing. Instead of always using Luria when you have an extra turn, there are techniques to avoid playing her when you can see your next turn's moves or when you have Fediel in your hand. Fediel drawn from Luria can heal full
@Severity1993 Thirdly, regarding this spell, since this deck has Sandalphon as a finisher, I believe this spell should only be used when you can't play Sandalphon and when the game ends with its effect. Considering these factors, I think this spell also has a limited role.
@Severity1993 Also, its Super Evolution has competition from cards like Belial, and while it's powerful in turn 10 as it pairs well with cards like Fediel, considering it's only a turn 10 card, its range of use is too narrow.
