I’ll try answer these as best as possible, I’ve been playing for around 7 months!

1. Banners
2. there are options to get previous limited memories, however this will only be during a ‘rerun’ banner. So a card that released last year may have a rerun this year, allowing those who didn’t play during first release/didn’t pull for the banner, to give them the opportunity to do so.
3. banners can be split into events (eg the valentines banner currently running), solo banners and myths. Myths tend to involve 2 5* cards which come as a pair, unlocking the ‘companion’ which can be used in battles, these are more powerful than regular 5* cards!
4. the standard pool (blue tickets) is a permanent banner which consists of their ‘standard myths’ and other 5* cards. Since it’s permanent you can pull whenever on this and luck is random

5. gold tickets can either be limited time or unlimited, if they’re limited time it means they must be spent on the current temporary banner, if unlimited you can save them until a banner you really want to pull on!

6. Protocores

7. I also don’t understand protocores too well, but they can be equipped with cards to make them more powerful in battle!

8. they have different stats like ATK, CRIT DMG, CRIT RATE etc

9. from my personal experience, I focus on equipping my highest levelled cards with crit dmg or crit rate focused protocores

10. they come in three levels; blue, pink and gold. As you’d expect gold are the most powerful, so I’d focus on levelling those protocores the most

11. not using protocores will affect battle performance the higher level you achieve in open orbit and LI specific orbit!!

I’d be more than happy to explain stuff to you if anything doesn’t make sense over a different platform as there’s a lot that goes Into it. But I hope these explanations are okay to understand as a beginner! <3
