It seems most sets will have to drop the Explosion :'(
im pretty sure metagross' explosion was the hardest non-boosted attack in the game.
I think the choice band set has some potential with MM, Thunder/ice punch, hammer arm and earthquake. Maybe im missing something but i reckon that would be a decent set coming off metagross' 135 base attack. Metagross hasnt really gained many attacking options too.
I am so sick of dream world abilities.. OMG, they give metagross light metal and milotic CUTE CHARM and then they give bidoof Inconsistent raaaaage
2 of my fave pokes getting useless abilities and barely any attacking options.
But the claw sharpen set looks promising, we can load up Metagross with semi inaccuate moves and fix his accuracy and attack. MM might not be from the best attacking type but it certainly hits hard and the attack boost is nothing to laugh about on a already 1+ and almost fully accurate Meteor Mash coming off metagross
Choice Band is superior as it does not require setup time. Setting up is basically a call: "SHANDERAA COME IN AND OHKO WITH OVERHEAT LOL!"
Of course, you can play Wifi where the Shadow Tag Chandelier bastard does not exist, but then the boost isn't really enough unlike SD which boosts +2 per turn.
Also, with a Choice Band/Iron Ball, with a little prediction you can TrickBand/Iron Ball an incoming Shandera and use your nifty new item to kill the Chandelier.
