It turned out that one variant of this file was an underdog. I was getting wins without noticing it at first and i check the underdog list to get my last 2 wins for the underdog.
I usually don't bother with the underdog achievement it's really troublesome to go through that giant nasty list. >_>
Anyways posting this version in hope it might help at least few iczers to bypass the stress and unnecessary burden of going through all the trouble to make a working underdog file:
Feel free to improve the file and use it for yourself. @_@
The way i usually open was: miffere (lv 4 refess) > keseran > spined piglet or let stuff die by playing recovery powder > more piglets or mamoth > verlaat to kill one enemy unit (usually works a lot better if miff / kesseran are still alive, more max HP hate)
Fool around as you please, try to make the opponent swarm the field so you then drop a burning sun on him. It takes basically 5 dead units until first leily is activated. Keep that in mind (although it's obvious).
Also there's the fun tactic of just swarming units and when you have enough SP banked you play game over, let something die if you have to.
Often i played game over and burning sun one after the other. Totally ruins the opponent.
Wish i had kaldaro or resourse SS for last.
Leilen SS is still sort of good vs EN. You can tear them apart with that SS alone.
Well anyways good luck with your Underdog challenge. It's really horrid to have to play it in this environment.
Every card aside from like the hand of god, are underdog cards from what i remember.
