well, nice combos.
i'm not exactly getting your explanation of the slaking+banette combo, but it's trUant, not trAunt.
pika+ludy-looking fine, just you don't need rain dance on both unless you're a little more than paranoid. but, it works.
blaz+meta-yep. i see your plan. make sure they don't ko meta or else you're left with a 1 hp blaziken and two opponents left, unless you downed one first, but still you'd be at a pretty big disadvantage if their remaining pokémon is an electrode or whatever that is faster than blaziken.
muy solido. =D pardon my spanglish.
