Looking forward to the next season! My favorite of the last half of season one would have to be Scott vs Sci-Twi, with Vader vs Tempest being a really close second.

As for hints;

Stupid duos; Snips & Snails vs Beavis & Butthead

Selling products; Flim-Flam Bros vs Billy Mays

Treasure hunters; Daring Do vs Indiana Jones

Those are the ones that I could guess.
