I know what you mean, but I want to catch a magic guard abra, which means I have to make my sync pokemon faint, which means everytime I deliver an item i have to keep it fainted, I use lots disconnections mid battle to teleport to the pokecenter for faster travels, which makes my natu heal, so it takes some time to make my natu fainted everytime i deliver an item. That's why my suggestion would make it easier to use trace ralts, or roleplay on abra or evolution syncs.
