Here's my team!
Blaziken for his speed boost shenanigans; Meganium for dual screens & terrain control through Grassy Terrain; Feraligatr for hitting things Really Hard with life orb and sheer force; Magnezone with assault vest to facetank almost any special attack; Slowbro for setting Trick Room as outside of Blaziken no-one has speed investment on my team; and Mega Steelix to become an absolute monster with Curse in Trick Room.
