>>33220906Well the nature chart is already posted. Mew will always have 5 perfect I.V's instead of 3 but you need to fuck around with arbitary code injection to get it to import. Shininess is determined by D.V's but the attack and defense requirements are swapped from gen 2.
TM wise the only thing to get excited about is Body Slam Sheer Force Tauros but there are a few fun things like Bubblebeam Cubone that can become a bubblebeam Alolan Marowak.
Also don't think about balltism as gen 1/2 don't save the ball so imports will always be in a pokeball.
