4th Gen What to do after you beat the elite 4?

[WolfWrath]

Immediately after the elite four, I caught a bunch of stuff not available
before, started chaining, and leveled up my team to lv. 100.

I just beat the elite 4 recently, so I didn't do any of those things, but im planning to do a lot of them.Im finishing my pokedex right now.( I need only manaphy)yay!!:cheeky::)manaphys hard to get.:(

I suggest unlocking random events, like the Flame Plate and book in Canalave Library activated by event Arceus, or capturing Regirock/Ice/Steel with the event Regigigas (both Platinum only).

I just worked on training my team in the new routes were unlocked. After all that was done, I would just hatch eggs and raise Pokemon.
