octane and sandstorm kinda negate each other, and i gotta assume it's pre movie or your run the risk of Blitzwing not being a Decepticon.
Broadside seems an easy matchup with Astrotrain, and i think Springer along with blitzwing are the best fighters.
Stats make me think Blitz is gonna loose to Springer, and if altmodes are used, Astrotrain may just beat out Broadside in the sky.

if all else fails, Springer's exp leading the wreckers seals this match. It really is kinda one sided considering whose responsible for the tec.
