Meanwhile, I'm continuing to farm GP; I just ran a high-roll deck on Dashka 4-1, and I only lost the mid-shadows because I bricked and couldn't find the right card sequence. It's a terrible deck, of course, lol.

Loken, how is your portal handling the Dashkas?

This is just... incredible.

I remember that Dashka was the first deck I used to reach a decent high rank, thanks to Neyechka for that... So it's even symbolic that I got my first 5-0 with it.
