I noticed a few mistakes.
1) Gligar`s HP should be 57 (16 + 16,5 + 6 = 38,5)
2) Gligar`s attack is 3 and Elgyem`s Defense is 2,so the damage from each move should be lowered by 1,5.
Not like these will help much though.....
Trick-Room -> Recover -> Psychic
If a combo is ordered,use Recover that action and push-back.
