Power Spot is an underrated ability that allows Stonjourner to power up its partner's moves. Stonjourner can bring both offense and defense with its natural bulk and Wide Guard being a great defensive option in general, as well as spamming Rock Slide for chip and flinch. Wonder Room has weird synergy as it lets Stonjourner convert its Physical bulk to its lacking Special bulk as well as flipping other mons with only 1 good defensive stat. Power Spot can be skill swapped to allow for other plays.
