Which Pokemon much deserves a new Mega Evolution

Mega Jirachi will have bigger ribbons and the head will have a closed eye (not a real eye btw) on the tip of the head is where the eye is at it's just a gem that looks like an eye by the way the back of Mega Jirachi is a big extra star for extra detail and decor and the body itself will have a cult-like hoodie (not a hoodie and mega jirachi is not a part of a cult) then to the back again it will have wings and that's all pretty much

Good idea, also, the attack animation could be similar to Mega Medicham's where the ribbons strike forward
