What do you predict:
What will be your top favorit card to play with?
What will be the most toxic card to play against?
I’ll start:
top: Jim Raynor
Even if starships will never be good. I like strong cards you build up towards, for a huge payoff. Combined with Thor it might be a functioning wincon.
toxic: Viper
Imagine it pulling your Dungar, or Kil’Jaeden, or Odyn. It has the potential to destroy your wincon and randomly end the game.
Edit 2: I found out Viper exists.
We already have dirty rat which costs 2 mana and you never see it played, so don’t worry about Viper. Yes it has a nice effect by giving reborn to the zergs but you don’t have that many Zerg cards to benefit from that most of the times. Ghost will be a more toxic card I think.
I had Ghost as toxic and then edited it later when Viper was revealed. Both cards are problematic. Imagine someone combining Ghost with Shudderblock. 
Oh and Dirty rat is played and reliably hits my Kil’Jaeden every time.
Whats your favorit card by the way?
I thought of Shudderblock and Ghost too. The design is either OP accidentally or they think it’s exciting to be temporarily OP before a scheduled nerf. In either case it’s dumb game design.
There’s also a chance to limit Ghost to 1 burned card, but I don’t know if they have the intelligence to think of that or they’ll wait for thee actual players to hand-hold them again.
All the predicts are known in advance
