Alright then. Since someone else already mentioned the best way to collect Fireworks is by doing Advanced, guess I'll keep there until Ultimate Phase 2 is up. And as a plus, you already get a couple of crystals there.

I think the only good way to get equipment slot for a specific 5* is to save up fg and spend it on limited gacha. On the other hand you alway get random 5 * on gacha and ticket.
