Azumarill and aqua jet too. Charizard Y is much easier to bring out and have the benefits of sun and ridiculous sp. atk, which makes it easier to transition to mega evolution without dying on turn 1 since it's water weakness/sp. def is patched up quite a bit and houndooms speed is an issue before mega evolution. You could try building a team that covers houndooms weaknesses, but its much easier to do that with charizard y.
