My ally, it was my Dragonite with Slip Through against my Lugia with Safeguard/Protect/Substitude/Fast Guard
I'll test Wide Guard and defence boosting moves tomorrow.
Are there any major game mechanic differences between attacking your opponent and your ally?
I need to know as i'm testing basically anything by attacking my ally in double battles
I did it twice against each pokemon, just to verify if i calculated the damage right.
All these pokemon have 216 defence as i found it easier to see the cutoffs (i suppose this is easier for you as well).
I couldn't do Dusknoir as my pokesav can't let it have 216 def or lower so i replaced it by Graveler(105kg)
