In any case, besides the obvious Dragon Dance Charizard-X, I think I'm looking forward to testing out this version of Charizard-y:
name: Mixed Attacker
move 1: Flare Blitz
move 2: Focus Blast
move 3: Earthquake
move 4: Fire Blast / Hidden Power Ice
item: Charizardnite-Y
nature: Naughty / Naive
ability: Blaze (Drought)
evs: 252 Atk / 4 SpA / 252 Spe
A Charizard-Y with maximized Special Attack has no way of getting past Blissey, Chansey, and most other special walls. With Charizard's increased Attack and Drought to boost Fire-type moves, however, it can very well afford to use physical attacks, as dumb as that sounds thanks to Charizard-X and that huge bulging Special Attack stat. However, Charizard-Y's huge Special Attack also comes into play; because it's so damn high, Charizard-Y doesn't really need to invest into it, as it can naturally hit hard with Drought Fire Blast alone. Notably, its uninvested Special Attack reaches 355, which is more than its Naughty maximized Attack.
Anyhow, one of the main pointers of using this set is to lure in get by Blissey and Chansey rather easily; sun-boosted Flare Blitz does a huge number on both of them, with the former being nearly OHKO'd
(83.89 - 98.92% with Naughty,
76.84 - 90.33% with Naive) and the latter being 2HKO'd, but unable to abuse Wish + Protect effectively (
51.98 - 61.36% with Naughty,
47.3 - 55.82% with Naive). Focus Blast is used over Brick Break since it has similar damage output to it on Tyranitar in sandstorm, and generally gets by common physically-defensive Rock- and Steel-types easier. Earthquake is for the occasional Heatran and Chandelure. In the last slot, Fire Blast also manhandles many physically defensive Pokemon that might otherwise survive Flare Blitz (read: Conkeldurr and Hippowdon), and has higher damage output than Hidden Power Ice when resisted in sun. Hidden Power Ice is only really for Salamence and Dragonite, and with its BP increase, it might disappoint.
As usual, it needs entry hazard control. Specifically, it really appreciate Rapid Spin support (then again, what common draconically-based mixed attacker doesn't?), and enjoys some entry hazards of its own, since without Stealth Rock or Spikes it can't land an OHKO on Blissey. As a disclaimer, the reason why'd you want to use this is to summon sun (and get rid of pesky rain or sandstorm if they're detrimental to your team) and because of the lack of recoil; other similar mixed sweepers have issues since they have to take LO recoil in addition to passive damage.
