For split faction champions, can I put them in split battlegroups that don't have both races. For example, can I put a risen yeti in a fw and ud battlegroup
Awesome, so the fact that it says I have 4 different races in my bg doesn't make it unuseable? For example in my ud/fw bg I have risen yeti so it says I have ud, fw, and st cards in my deck
id recommend just running ff if I were you. Idk why the heck people run splits but I don't think its worth it...
Depending on the splits they can be better than FF but thats not always the case. Splits in theory have double the potential cards to draw from but they also limit the number of things you can take from one faction. The key is to find to themes or runesets that have similar strengths but different weaknesses that allow you to build so one side covers the other sides weakness while still complementing the strengths. Splits only really get out of hand when there are enough runes that are "meta" enough that there are no weaknesses.
