Chuck's Reviews Transformers Earthspark Flip Changers Swindle and Soundwave
 

Flip Changers is a bit of a misnomer, I think tap and change describes better the technique needed to transform these figures. Swindle borrows a few design cues from its Combiner Wars figure with a softer pastel color pallet. Soundwave's design borrows more from the 2015 RID cartoon and the Prime-era Stealth Jet. As with previous one-step changes these make for great desk toys, but please, don't throw them in the air.
