Game #51864173 on tokyo.
I play a Treasury, and I play an Expand using Way of the Frog. The cleanup dialogue correctly gives the choice to order the topdecking of the Treasury and the Expand, but the art shows a Scheme next to Expand; there's no Scheme in the kingdom.
That was a shortcut taken that may be confusing more people than helping, it seems.
From the game's perspective, Scheme's effect and the Way of the Frog effect are the same: You get to topdeck a card that doesn't have this ability by itself. So the Scheme picture was used to denote the general effect of "topdeck a card by an external effect", which includes Scheme and Way of the Frog.
