Well Tyrant is Galactus' kryptonite, so Team 2 is fxxked in that regard. But then again, Galactus can face off vs the IB (IB couldn't use his opposite trick on him) while Arishem beats down Tyrant (I believe Arishem is more powerful than either Galactus or Tyrant, he is the "mightiest" of the Celestials after all).
Could go either way depending on who faces off vs who. Split 50/50.
