well if they did stretch as far to make tripple type mons which i doubt ever happens tho i wonder what tri type mons would be the ultimate tank lol.
atm Bug/Steel and Grass/steel types are the defencive mons out there if you think on typing resistance and if you add another type to them then i dunno what type combos it will make it really defencive lol.
oh or how about the ability to have a second hold item lol
now Arceus with both bug and steel plates would make one strong, hard to beat legendary if fire aint used against it lol. --- 3DS FC: 1355-7222-3011 ...Black FC: 4942-5368-2220 PSN: BurningLance_2
