the thing of team building is having a center pice and a team who this pice can fall back, example for a team with blaziken as a core you can always count on a dark water mon for coverage, and someone with a strong ground STAB, with this you should be good to go example Blaziken , Nidoqueen and sharpedo, they work preaty well together and the better part is that nidoqueen is a event mon, so you can soft reset for a better nature as atributes, take her and EV train her to be a beast, aqua gang will give you a nice carvanha ( same deal soft reset for a nice one ) and you will have a solid team with 3 free slots for rotation and slaves, so you can bring a teleport mon, a flying slave and a pick up mon or whatever you wish for.
But anyway we are here to help so say us your wish and we will brainstorm you a brand new team.
