Please rate my Pokemon Soulsilver Team?

So far, not a bad team. As much as I like Houndoom however, I'd say yours doesn't seem to be shaping up as nicely as it could. Unfortunately, your Ampharos seems like it's not fast enough to go first, and not durable enough to take more than a hit or two. If you're trying to raise an individual stat that your Pokemon excels in, you should give them the proper medicine (protein, calcium, etc) and also equip them with the appropriate item for leveling (Power Bracer for ATK, Power Lens for Sp. ATK). You can also try equiping a Pokemon with the Macho brace and then fight whichever Pokemon corresponds with the stat you are trying to level up (rock Pokemon for DEF, fighting for ATK). Using these tricks, try to aim to get the stat you are aiming for as close to 200 as possible by lvll. 50 (my lvl. 50 Gallade has an ATK of 186). That will give you a goal to work towards. I would also replace Ampharos with Raichu and breed it to learn Volt Tackle. All in all though, good team. I like it. The rest of your Pokemon seem good
