From what I have given, 10 Blue Shards got me Rain Dance. So I think you get TMs that the type corresponds to the color of the shard:
Try Lucario/Zangoose/Absol -> Rhyhorn -> Cubone.
Red: Sunny Day
You can go underground anywhere as long as you're not inside a building or cave or something like that. Just use the Explorer Kit in your Key Items pocket.
None really, as far as I know. It's probably just to give some variation, just like your trainer says a few different things when you withdraw and send out your Pokémons in a battle.
When you speak to it in the cave and it runs away.
K, thats what i had figured but thanks :)
First you need to send your Pokemon you want to trade-evolve to the GTS. Next, you seek/trade for any Pokemon like Kadabra that evolves when traded.
I'm not sure about the first two, but my friend uses some pokemon with 252 in each stat in the battle tower and it works fine for him, so I would assume you can, at least for stats. My guess is that it wont work if you have a pokemon with illegal moves, abilities, or stats that are higher than normal (i.e. an impish skarmory with 300 special defense or a suicune with 500 special attack or something)
