>One Mega that I can get before postgame without trading

You're in luck. The game hands you a hasty mega lucario on a silver platter

>Something that can surf
Go water starter. versatile/Broken

>Something that can fly
The generic bird is actually amazing this gen

Afaik the only megas you can get before postgame are the Kanto starter, Lucario, Abomasnow, Aerodactyl, Ampharos, and Gengar

Wingull for surfing and flying because Wingull is cute, available early on, and can learn both fly and surf.

Just nuzlocke it.

>>26526282
Not doing a Nuzlocke.

Aerodactyl and Heliolisk. The former is both a Mega and can fly, while the latter gets surf. And they're both fast attackers.

Talonflame? Amazing?

>>26526186
How about playing through the game, catching as much as you can, and assemble a team out of the ones you like the most?

>>26526186
Get Mega Aerodactyl and Clawitzer.

Clawitzer can use Surf well and rounds out his moveset well with powerful coverage moves. M-Aerodactyl takes care of your other two criteria, and does it fast as fuck.

Mega Ampharos
Poliwrath
Charizard
