the core doesn't really need much outside support but rather acts as a nice defensive backbone that balance teams can fall on while providing aromatherapy and stalth rock. one problem with it is that it can't really deal with bulky boosters such as spiritomb or uxie which is where pawniard and gurdurr come in. they can outmuscle most set up sweepers that the core can't handle while being able to act as win conditions. cryogonal helps deal with hazards and rotom revenge kills stuff
