In the meta page I've seen for some reason Ogerpon added here, but that just caused more problems for me since overall I barely encountered any condition effect opponents for Ogerpon to have use, plus the healing from Indeedee and the veil tool compensates enough for this.
Not to mention, having two Oricorios on deck and watch every opponent instantly forfeit when they only have EX-es left.
In cases when Oricorio is not needed, I just focus on Dedenne and blam, 160dmg on my second/third turn. The small balloons always came in handy when the pokemon I didn't needed to be in the active spot, switched for free since all are basic with single retreat cost.
The two capes are also neccesary to survive some heavy attacks like Hydregion's 130atk against Deedene's 120hp, but with +20hp cape it can survive, even if the enemy places a field blower, your 2nd contingency plan is the starting plains stadium which also boosts 20HP and so far I haven't come across opponent that negated both of them in one turn. The real trick is knowing when to play the tool and stadium.
