Hey guys I got a few questions. Later in the game, who in my team (easy..

First off; You have the same team I started with- so I can help-

For moltres and articuno- Make sure you have about 2 reviver seeds just in case.
You should be around level 30ish especially if youre preparing for ahead.
Raquaza, was the EASIEST of all bosses I had.
While in sky towe, I suggest trying to recruite a shuppet.

Each dungeon is different, but look at a walkthrough for all the "bosses" and the best to beat, it's too much to put here! Mudkip is a good starter and will help you easily knock out most bosses, Pikachu can help with the others (like Articuno). Make sure you keep your levels high, especially before you know you're about to get chased for a while, so do some rescues and level up your team early!!
OK, my team too! I had no problem with Ice Beam against the rest, and against Rayquazza I don't remember Pikachu helping out, either. I just kept hitting him with Ice Beams. Actually Blizzard seems to be the better move on paper, though, so maybe that'd be best. But I think my Mudkip was a pretty high level, so get Pikachu in the right spot to help out and limit his moves to only the ones that will help you against most of the others and Rayquazza. Also, thrown items (not gravelrock, it doesn't do enough damage, but anything else like sticks and iron thorns), used first when a foe's further away will give you a good head start. And use a couple of Special Bands for your Pokemon-they'll up their Sp. Attack by 12 points!! Ice Beam:15 base attack, 88% accurate, 8 PP/ Blizzard: 24 base, 84% accuate, 10 PP. Both have a 12 likelyhood of getting a critical hit. Ice Beam can be used in a straight line far away, where Blizzard you must be within a 1 tile range in front of the foe.Your decision! Here's a couple of WM codes:
Client: Nidoran(F)
Objective: Help me.
Place: Silent Chasm B9F
Difficulty: D
Reward: Ice Beam
Wonder Mail:
? ? K C X (M) X ? 4 P P 9
! F ? 9 P 4 7 6 P H ? W

Client: Meditite
Objective: Help me.
Place: Mt. Thunder 10F
Difficulty: D
Reward: Ice Beam + ?
Wonder Mail:
1 ? C K 8 (M) T ? ? + R 2
H R ? C J ? 7 6 P N ? W
You may have to check the BRT (Non-SOS) forums because I looked and didn't see any WM codes for TM Blizzard. I hope someone will make you one or help you find one there if you cannot.
You can only use a particular wonder mail code once. If you see missions that you may want to do later, but don't have room or aren't ready yet, just write down their codes and enter them later-that you can do, as well as getting WM codes from elsewhere-like in user submitted cheats or in the walkthrough section, or in the forums.
Do you want him to learn Dig?!? It's really up to you. It's not a move that can be linked if you do that (which may be another way to get the others and Rayquazza as you get 2 turns for each of his with moves linked, but you need plenty off PP and Max Elixir to keep that up for long, so you could use a link box to link some moves right before you get to him.) and it has a 12 attack base points(pretty high in this game), 12 PP, and 100% accuracy. You can always try it out without saving and get rid of it by resetting if you don't like how it works for you...just don't use it around foes who like to use earthquake, bacause Pikachu will get double damage if he's underground at the time it's used, and he's alredy weak to ground moves!!
Rayquazza wasn't as hard as I thought he'd be, though, so depending upon your Pokes levels, it may be easier than you think...Good Luck!
