First let me start off by welcoming you to Poxnora. I have been a part of this game since just after the Savage Tundra expansion. As of this writing that is a little under 8 years now. Sometimes I get questions on how to make an appropriate battlegroup; BG for short. GabrielQ has made a wonderful, and more in-depth guide here. The way I make bgs are a little different than most. This works for me. Let me explain. A Basic bg is made of 30 runes. Compiled from Champions, Spells, Relics, and Equips. Of these you want around: 15 Champions 6 Spells 3 Relics 3 Equips 3 Wild (15 Champions is my standard minimum. The amount of Spells/Relics/Equips tend to vary.) Within the bg you need to have at least 1 source of each: Detection, Anti-Equip, Anti-Relic, and at least 2-3 runes that can disable/debilitate champions for a few turns. Wild runes, are just runes that you put into the bg to tinker with the bg. I believe that a bg should be "finished" at 27 runes. This allows you to have 3 interchangeable runes that can be used to test combos, synergy, add new expansion runes ect... Without directly affecting the how efficient your bg is. I might add to this more later. However this is effectively how I make a bg.
