What do you do before Teppen eos?

I'd like to know what should be done with our account and resources so it doesn't go to waste.

- what should I do to ensure I can play the offline version? Should I download it and link my account or something, or register somewhere?

- what do you guys do with your resources? Coins, souls, crystals? (I'm a bit bummed out on missing out on the skin pack, I thought it was ending at the same time as eos)

- anything else I should do? Also, what other card games are you guys playing currently?

Cheers :)
