I suppose mixed sets (ones that include EV investment, I mean) are viable on both mega 'zards.
However, call me old fashioned, but it feels like people are wanting one poke to do way too much. I'd stick with EQ on Y over flare blitz, honestly, and no att EV investment. Is team support overrated now?
If flare blitz's purpose on Y is solely for blobs, I think it's a bad choice. Blobs can cripple you with paralysis, for one, and they're best taken on by team mates anyway. That massive recoil from it also really limits your survivability.
This is the set I am referring to that uses Flare Blitz, which is currently being pushed into
Charizard Y's analysis right now:
name: Mixed Mega Charizard-Y
move 1: Flare Blitz
move 2: Fire Blast
move 3: Hidden Power Ice / Earthquake
move 4: Focus Blast
ability: Blaze
item: Charizadite-Y
evs: 252 Atk / 4 SpA / 252 Spe
nature: Naughty / Naive
No weird 252 Atk / 252 SpA spreads, you absolutely need that speed. If you aren't using max attack investment on Charizard Y don't use Flare Blitz because you won't be able to break through Chansey reliably even with SR and sun in play:
4 Atk Mega Charizard Y Flare Blitz vs. 252 HP / 252+ Def Eviolite Chansey in Sun: 267-315 (37.9 - 44.7%) -- 4.7% chance to 2HKO after Stealth Rock
meanwhile max attack...
252 Atk Mega Charizard Y Flare Blitz vs. 252 HP / 252+ Def Eviolite Chansey in Sun: 333-393 (47.3 - 55.8%) -- guaranteed 2HKO after Stealth Rock
The point is that max attack Charizard-Y is a lure.
It is the team support. If you do not have an accompanying sweeper that is heavily walled by Blissey and Chansey, such as Sheer Force Landorus-I, NP Thundurus-I, QD Volc, or Tail Glow Manaphy; you are much better off using the standard max SpA wallbreaker.
Char Y with flare blitz is pretty cool, but I think you should team support (Ttar/taunt user/hazards) to help take out pink blobs. Charizard Y is just a big nuke and more often than not can get easy kills everytime it comes in.
I would agree. For the large majority of teams running max SpA will get you the most mileage out of special Charizard-Y. The big appeal about Flare Blitz Charizard-Y is that it can immediately remove Chansey from the game. Chansey isn't the most removable pokemon since it has huge bulk, reliable recovery, and a status immunity. While sandstream / hail, taunt, and hazards can all wear Chansey down, consider that Chansey is most likely going to be on very defensive / stall teams that can find lots of opportunities to rebound from those options with a lot more turns in game / high amount of support to Chansey. For example, the stall teams that Chansey is on will probably have a pretty solid defensive defogger to remove hazards multiple times in the match. It is a lot more work for you, so there is a lot more room for error. Charizard-Y's immediate luring removal of Chansey minimizes that room for error on your side.
