Thanks! I was just thinking of using this Charizard for in-game use. I thought of going with Bulldoze and Thunder Punch specifically as means to counteract Charizard's weaknesses (i.e. Rock & Electric and Water respectively). I mean I guess I could use Solar Beam to counteract the Water weakness, but it is a two-turn attack, and Steel Wing for Rock weakness...wait...I could always have a Charizard with its HA Solar Power and swap between Charizardite X and Shell Bell, but...to be honest, I really don't like that hidden ability on a Charizard, so that leaves me with Blaze. What I'll probably do is get a Charizard with it's regular ability Blaze, and then just rotate between having it hold both of its Mega Stones at a time, depending on the battles. If I do this, I'll include the Charizardite Y stone for it's Drought ability, using this and have it know Solar Beam so it'll take one turn instead of two. I just wish that Charizard's hidden ability was Drought instead of Solar Power, but we all can't have things the way we want it, right?
Also, would it be too much to ask as to how to use the IV calculator? Several of my hatched Charmanders already have all 6 31 IVs, including two pairs of male and female, one of which I'm currently breeding with.
