I remember playing this game back in 2010-2011ish on a Kindle of all things. It's almost like cartoon wars, but instead of a castle, you have giant champions that you can move around and when your champion dies, you lose. You can send out different kinds of minions and it has a more realistic looking art style. I've been looking for this game for a long time, if anyone knows what I'm talking about, please let me know.
