>>58645513I kinda doubt. Two other Megas have Mold Breaker, zero have Sand Rush. And Sand Rush has only been given to one Pokémon with more than Excadrill's own 88 speed (Lycanroc midday).
Mega Swampert is the only Mega to get a weather speed boost. So it's far from impossible. But Mega Swampert's base speed is 70. 103 is actually pretty good already.
