I am going to use just fire types to beat all gyms and elite four in pokemon y (I'm getting y). I'm hoping to train up a competitive fire team for online battling this gen, I managed to have an all fire team that beat my mates all water team before so I know that an all fire team can be done, I just picked fire types that could also learn some grass moves through tm and used sunny day alot to half waters effects. In pokemon Y I know I will use Fennekin, Litleo, Talonflame, the Torchic event pokemon for Mega Blaziken, I'm also going to request a chimchar from global trade to raise as soon as possible. I really want to raise a magby too into a magmortar but whether I do that depends on whether or not the magmorizer is easy to obtain. Really I want there to be either a global trade for items or a shop to buy all the evolutionary items in this gen as some of the rarer ones are a pain to come by. I'd also consider using charmeleon in my team, yes I know charizard is stronger but Charmeleon is probably my favourite fire type pokemon! Houndoom, Macargo, chandelure and Rotom in oven form are others I am considering for my team.
