Taliyah Lab deck.
This deck is irredeemably shit. Azir was really bad, but at least with his 3/10 deck you can still get some lucky rolls, ignore the main deck and try to play only using a secondary region. Taliyah is so much worse that you can't even rely on a secondary region to save you.
Is everyone at Rito allergic to playtesting? Or is this just another case of 200+ years of experience?
