Stalwart vs Valiant- Who to feed?

[okiwao]

I am ready to level up a new dragon to level 15, but I can't decide between Stalwart and Valiant. I want to hear from the community on which you believe is better for battle.
I still have trouble picking color combos to go against hybrids opponents.

Thanks 

Valiant has a better rarity advantage given it is Ultra Rare. An Ultra Rare champion is a great investment- my level 15 Light Mother Dragon is amazing in the arena.

Yep, totally agree take Valiant up, haven't regretted taking mine up:)
