Royal Guard is ridiculous OP

I'm surprised nobody has mentioned Anakin as a counter yet. His buff immunity also prevents RG from taunting. Plus, Anakin is frequently teamed up with Lando and Palpatine, which gives you two ways to block RG's taunt and an insanely devastating AoE that will kill everyone regardless of whether RG is taunting.

Remember, this is a game built around the concept of rock-paper-scissors: every toon has its strengths and weaknesses. As a player, your job is bring the right toons to capitalize on your opponents' weaknesses in order to ensure victory. If you find yourself having a hard time beating a certain team, it's likely because you're not using the right team to fight it.

A toon is only truly considered OP if it has no real weaknesses and nothing in the game is able to counter its strengths.
