Sapphire's Upgrade To Heart Gold

I grew attached to my team in Pokemon Sapphire and decided to send them into Heart Gold. I'm open to any suggestions for improvement. What they look like now... Any feeback at all is very much appreciated.

Your team looks solid. Not gonna lie though I would take explosion off of Metagross. Replace Explosion with Iron Defense.
