Jaxi is awesome. She plays so well with my Vanar deck that if she gets nerfed up the core curve, it may become difficult to play her anymore. She adds that extra threat even when she dies that makes the opponent decide whether to deal with it now if they can or later when I add Frostfire to it. I've had a few games where they opted the first when it appeared on their side and it proved to be their downfall as I stormed in their side and placed Snow Chasers and Glacial Elementals, blocking their path and mowing down their minions. Its fun.

Grailmaster was added to it too as a tech card and she wins fights that would have otherwise became a stalemate or me losing bad. My Vanar has cheap minions, Snowchasers, Borean Bear, Jaxi, etc and no provoke but as long as Grailmaster gets Ranged and Celerity, which is fairly a common roll, it seals a 12 damage force of death.

I've left behind my Abyssian deck and mained Vanar now. She's consistent in winning but I can't break through the ranks yet since she gets beat up by Aggro Magmar.

I've read about that in reddit. The only way to bypass that is to wait a bit, like 2 to 5 minutes, so that the person you just played against could find another opponent.
