Oh yea, I got the guide a while ago. I've only really used it to get the gist of the whole adventure.
I got Giratina yesterday, and am just training my guys up now. I almost killed it at first, then I remembered at the last second to throw a (the) masterball at it.It's got some crazy powerful moves, pity they only have like 5pp each. It's quite a monster, I havn't met anything yet that I can't beat with it. I got it at level 47. It's funny though, that when I was fighting it, it was pretty easy to smack down.
I want to get the 8th badge now, but the gym leader isn't there, so I'm just going to work on catching the 3 lake legend pokemons instead for now. They're easy enough to kill for my team, but I just can't get the damn things to stay in a ball.
