One of my favorite things to do is to imagine what cards will come out in future chapter packs. The current CP series has me more excited than usual, because it focuses unique characters that should be more predictable than scrubby non-uniques. Here is my attempt to guess what "champions" we will see in this series (other than those already spoiled). I'm also thinking/hoping that each house will get a unique weapon, based on the first CP.
Baratheon:
Robert Baratheon (I think a non-renown, beast mode Melee Robert would be awesome. Easier to balance with so many other good Bobs).
Brienne of Tarth (performed well in the melee)
Oathkeeper
Greyjoy:
Asha (good with an axe)
Theon (good with a bow)
Lannister:
Bronn
The Hound (did well in the joust)
Ser Garlan Tyrell
Widow's Wail
Martell:
Arianne (good at scheming)
Doran (a champion at scheming)
Quentyn Martell (because we haven't seen him yet)
Anders Yronwood (one of the most important Lords)
Stark:
The Greatjon
Ice
Targ:
Strong Belwas (background in pit fighting IIRC)
Oznak zo Pahl (had a CCG version)
Wasn't there a Valyrian steel sword in the Targ history books that caused a rebellion?
