I'm playing Pokemon Platinum version now. I think my team still has some weak spots because I just use original move(i think) and I don't have much experience about this :P. I would like you guys recommend please :)
Metagross - (Hammer arm, Meteor Mash, Zen heatbutt, Earthquke).
Blaziken - (Blaze kick, Sky uppercut, Brave bird, Flare blitz)
Dragonite - (Aqua tail, outrage, aerial ace, safe guard)
Tyranitar - (Crunch, earthquake, rock slide, ice punch)
Porygon-z - (Tri attack, discharge, signal beam, physic)
Milotic - (recover, ice beam, surf, toxic)
That's my team. I know that my Pokemon's moves are a bit weak, so may you tell me what moves should I change? :)
