Happy Independence Day!
You're doing well to get into Champs III with Wild. In both Modern and Wild, I feel like there are times where I get a really good run, or I'm just losing constantly... but I haven't seen too many scenarios where I'm winning every 2nd game.
Do you have either of the new Rebellion summoners?
Nope, I'm mainly running the Chaos Legion summoners. I don't have a lot of Rebellion cards, let alone leveled up ones. I do have an okay mix of Untamed and random reward/promo cards that make it a more decent Wild deck.
