You got Antimagic before first Master Enslave, so it wasn't that bad, i think.
I'm learning a lot about endgame myself, though (on a normal scale, not crazy one like in Perpetuality).
dammit...I must've misclicked so the remnants of my army didn't move and promptly got owned again. Most of them were diseased anyway though.
Agartha will probably eat me pretty quick, but I'll keep going until that happens.
