I tend to use Silurids, Waldgeists and tots together depending on what strategy/schemes I need to achieve. If Breakthrough/Plant Evidence/Line in Sand comes up I'm taking Tots and Cherub to get the (0) interactions to place more schemes.
Silurids are there to help grab objectives, leap out of the way or leap onto objective, next turn interact, leap, interact.
Waldgeists are there for cover generation and the huge melee range they can offer.
Have yet to use Juju as I don't like the current model but will pick up the new plastic Zoraida set.
