>>23106213Yes it does you fucking delusional faggot:
>252+ Atk Life Orb Blaziken Knock Off (97.5 BP) vs. 0 HP / 0 Def Mew: 286-338 (83.8 - 99.1%) -- guaranteed 2HKO after Leftovers recovery >252+ Atk Mega Blaziken Knock Off (97.5 BP) vs. 0 HP / 0 Def Mew: 272-320 (79.7 - 93.8%) -- guaranteed 2HKO after Leftovers recovery At max it's only a 5.3% difference, but mega Blaze actually eats up your megaslot loosing the opportunity cost to use megas that are unique to their base forms like Salamence or Diancie.
>>23106190Except Mega Latias is actually good if your using her for the increased bulk. She can pull some shenanigans with Reflect Type against her counters, has utility like Roar, can even even do a Calm Mind + Stored Power set better than the base form and beat Chansey 1v1 if she carries Refresh and a recovery move. There is no reason to use Mega Latios offensively or defensively over his base form and mega sister. Which is why hes considered as one of the most underwhelming megas for the slot.
