The good thing about TR with team preview is that you get to see, or at least have a guess at what the opponent will try to stop you setting up with. About imprison chandelure, the best way to stop it, is either with a faster imprison chandelure :p, (though i am not sure how that will work on a TR team) or to use sucker punch, such as on druddigon, even then though you have to watch out for the sash. Another alternative, is to have a whimiscott, to taunt the chandelure before it imprisons, u could even trick room with whimiscott, (obviously the problem with whimscott is, that is it weak to fire). The thing with VGC11, there is no best strategy, there is a counter to every strategy, so just learn your weaknesses, and turn them into your strengths. With amoongus, the only thing i can think of is taunt, but them there is still the potential it is carrying mental herb, i don't think anything can ohko it. Or alternatively you could always try sporing it first :p
