Stupid Mistakes

Has anyone found themselves doing these?

I've attacked my mareep thinking it was the enemy xD I've also gone into the kingdom of viperia with 4 psychic types, 1 jigglypuff and 1 vaporeon thinking it would be a good matchup due to them being a poisen nation. Then I accidentally let the spiritomb gain a banner.... so my psychic types couldn't budge it, their attacks do absolutely nothing against that typing, same with jigglypuff. Which meant the only pokemon that could even damage the spiritomb was vaporeon. Luckily I had yet to use my warlords ability, otherwise I never would have won that battle, as it was there was only 2 turns left when I obtained the final flag
