>>28793207I believe this is the most economical/optimal setup that covers the most ground, assuming Jangmo-o becomes Dragon/Steel.
Dragon/Steel resists fucking everything, and immune to poison. Bird covers both weaknesses, others cover also.
A-Marowak with Lightning Rod immune to normal, fighting and electric. Resists fairy, immune to burn. Team easily covers weaknesses.
Electric/Flying an insanely good type. Immune to ground and paralysis, wrecks other flying types. Team easily covers rock and ice.
Ice/Fairy has massive STAB coverage. Immune to dragon and freeze. Marowak resists 3/4 weaknesses, others also cover them and rock.
Bewear eats phys moves for breakfast, immune to ghost, versatile fighting STAB + near-perfect neutral STAB coverage.
Lurantis for grass status immunity. Rounds out defensive/offensive coverage, likely has either its own status or cleric moves, probably both, and good speed to use them.
Only thing it really lacks is STAB ground, but Marowak certainly gets ground coverage, plus its electric immunity.
