Oblivicorn doesnt have mega too?

[Lord Windos]

I imagine that, once everything else is added to the game, and all the bugs are ironed out, they will finish adding the mega evolutions to the game. Diakatuna is supposed to have one, and Oblivicorn not having a Mega, when its other evo does, its a rather big discrepancy. Only time will tell if those megas will be added, though...

As for natures for the Oblivicorn, I believe it would be better to go with Jolly, as it needs every bit of speed it can get against the other major threats in the game (Hello Tracton and Archilles!). Choice Scarf + Max SPD IVs + Jolly makes it a very fast killer, though one that has to switch out a lot. Go with Adamant, though, if you need an Oblivicorn that can break down walls easier if you already have a speed demon on your team.
