Sure! My biggest recommendation would be to scrap energy base for something with a little more direct utility for the cost. Gigan, Mog57, and especially shinden are some really good ones.

Orga’s decent, but at that level he really can’t make use of his tanks nature, along with being hampered by being single-target. Anguirus does much of what Orga does but better, minus the revive obviously, and for less cost.

G99, oh my poor G99 I love so much, he has been power-crept to oblivion, so he doesn’t really shine too well right now unfortunately. Based off of the playstyle I’m getting from your team, Kiryu Kai or Tokyo G54 would probably be better options for their cost.

-1 is cracked, so absolutely keep him, Mog94 is game breaking, so definitely keep him lmao. GMK is also insanely good right now so keep him. KG19, in my opinion, is better as a unit, but it does have good range and certainly good damage. SpaceG is also decent, but primarily good for the purpose of buffing other units rather than being intrinsically good.

Finally, I would recommend that if you want to keep Orga, switch him and KG19. Orga’s a great leader because of his ability.
