[DISCUSSION] Does Solar Power matter on Charizard Y?

[Black Waterfall]

There are very few cases I can think of in which pre-mega abilities can have some strategic uses. Unfortunately none of them involve Charizard: 

• Intimidate with Gyarados, Salamance, Mawile;
  
• Prankster with Sableye (In Gen 6);
  
• Speed Boost with Sharpedo;
  
• Chlorophyll with Venusaur;
  

In order to make use of Solar Power you would have to both prevent Charizard from mega evolving and have a sunny weather, but since usually there is no reason not to mega evolve to Mega Charizard Y in the first round and have an additional sun setter in your team, there is almost no difference between Blaze or Solar Power in practice (all my Mega Charizards Y have Blaze).
