Just dropping this here, because I feel it's a helpful link for making your team, given many MegaStones are postgame only.
I took a look at the list and I am pleased to see that Aggron's Mega evolution removes its Rock-typing. Now it won't be taking x4 damage from Fight and Ground.
I am happy with Banette getting an evo, and I know they probably went for a mega for pushing the new mechanic, but I wish it had been a 3rd evolution instead, given that Banette is 2nd stage and had "space" for another evo.
In my opinion Mega Evos should have been reserved for 3rd stage, legendary and perhaps single stage (Mawile, Aerodactyl, etc.) Pokemon. Those mega evos for 2nd and single stage Pokemon could very well have been actual evolutions.
But I am not complaining because getting a Mega evo is better than not getting an evolution at all.
