Beating GL rey phases 1-3 WITHOUT ANY zetas, and no CPO/R2D2!

I know this might not be too useful for people that already have her but you can actually beat the first 2 phases without a single zeta required. Here is the strategy. The 5 members should be amylin( mine has 131 speed and just some meh mods to make her somewhat tanky and 0 t6(gold) mods at all), resistance hero Finn, resistance hero poe, zorii(I have mine 3 stars gear 9), and the required rey(jedi training).

First make sure this is the order of their speeds, rey first, Finn 2nd, poe 3rd, zorii 4th, and amylin 5th. Star the battle with rey's mind trick on their leader character (make sure this ability is maxed out) and it should inflict speed down. Then with Finn use strength of will( his 2nd ability) on Poe and idk if its because a bug but for some reason only the leader will counter when he is affected by that speed down, making Finn survive ( if 2 of the enemies counter attack Finn restart your game or go back to the main lobby and go into the phase 1 again(you don't lose energy anymore on GL events so you are fine). From there go with poe and use 2nd ability on rey targeting the main enemy leader, use reys abilities as you wish, use the mas recall from Finn to hopefully kill the leader and if not let him die with counters and finish it with zorii or anyone else. From there it just becomes a deal of using zoriis 2nd to basically nuke one of the enemy's, removing tm from them with rey, getting a few evades with rey and with amilyn try to either use her heal or 2nd to daze the enemies. It should take you a few tries but hey no zetas wasted and you can use them on the GL rey instead. I added a video of how the beginning play should look like. Hope all of you good luck!

For the 2nd tier is even easier as hux is the only one that would counter Finn at the beginning so same strategy all on hux, ability block the tanks, mass attack from zorii on weak pilots and overall a super easy tier.
