how to beat geo trio?

My Vader/Biggs/TFP can win pretty consistently with Tarkin as my capital ship. The strategy works best if they're using Tarkin or Thrawn. If their capital ship is faster than yours, just do TFP's basic to get Biggs taunting faster, but if yours is faster, get foresight up so you can dodge the AoE and almost immediately get a reinforcement (this only works if your capital ship goes first). I like to call Ghost first so I can regen protection on Biggs and stealth Vader for a bit in case Biggs dies. I always target Sun Fac first because he'll end up taunting anyway, then I usually go for Soldier then Spy. I have Slave 1, Silencer, and FOTP as my other reinforcements, but I rarely ever need to call in more than Ghost and occasionally Slave 1. The advantage of this lineup is that it gets to go/reinforce first, and Empire ships under Tarkin do some ridiculous damage. I've had TFP hit for upwards of 150k when two or three enemies were debuffed, I don't think a single ship in the game could survive that. I only see Tarkin and Thrawn lead geos in my fleet arena, so I don't now how well it'd do against the others, but I've had it work against Tarkins faster than mine.
