User blog comment:Smaugtastic/Secrets to Dragon Story/Tourney Battle Plan/@comment-28129975-20160606182354

I haven't seen Smaugtastic around too much lately, so I will go ahead and throw in my two cents worth here. I've done a bit of researching this whole question. I'm sure Smaug will chime in when they have some time.

Other than RS & Valiant, all the champions are pure. It seems those two each have opponents where they excel & others where they do not. (I don't know exactly why or how, but the addition of the second elements in their types affect this).

For all the rest, the only differences in fighting probabilities should be Level and Rarity. Obviously we want the rarest, "Super Rare" & the highest level of 15. We can't change the rarity, we just need to look at all the super rares. We can change the levels ... and the easiest way to do so, is the cheapest food costs. The cheapest champions to feed belong to food group “E”.

So I've gathered a list of all the "Super Rares" that belong to food group "E"… Inquisitor, Shaman, Warrior Princess, Warrior Queen, Warrior King. I think these are the best champs to try to advance to max level. Two others ( Battlesteed and Dueler<span style="font-family:Helvetica,sans-serif;font-size:10pt;line-height:15.75pt;">) are super rare and food group “F”. They would be the next best choices, although considerably more expensive to feed. Hope it helps & best wishes to you.
