I really want to make a semi competitive but mostly for fun theme 'Team Forretress' team
Ferrothorn - The Engineer With all his traps etc. General defensive / leeching
Ditto - The Spy A staple in my teams this generation as a general anti dragon or surprise to enemy teams. Totall badass with auto transform now
Blissey or Togekiss - The Medic standard wish pass
Gastrodon - The Scout double accuracy lowering, water absorption for pesky rain stabbers to boot. Never stays out long in rain teams for me to keep them guessing.
Ho-oh - The Pyro Burn shit with Sacred fire and stall them to death. Used to use protect but finding fly to be just as effective playing around
Heracross - The Heavy Choice scarfd, hit fast and hard, 1 shots nearly all that does not resist it, and cool coverage against pretty much everything, my favourite mon aesthetically and to battle with!
Want to change Ho-oh actually as I am not a fan of using legendaries, except the legendary Heracross
