I finally fucking got it! YES!

Only took me 10,000 eggs, so fucking unlucky holy shit.

Anyhow, how should I build this bad boy? I already have a defensive wall so I'm looking for things maybe for to work with it's Dynamax.

Also, I can't actually remember the best way to fix its stats (do these carry over to Sw/Sh?) and best way to do EV's is Festival right?
