I think I have this right?
Example: +Card token on Moat pile, Way of the Ox on board.
I play a Moat as my last action for some reason.
Token first gives me +1 Card, before I do anything. I draw a Smithy.
Now I choose whether to use Moat's effect or Way of the Ox's effect. I want to play the Smithy more than the Moat, and I'd like to not draw anything dead, so I can choose Way of the Ox, even though I already drew a card from the token.
So in this case, Moat can either be a vanilla Village (+1 Card, +2 Actions) or a Smithy (+1 Card, +2 Cards), but I get to choose which one I like best after I draw one card from the token. It seems like Pathfinding, while already very powerful, is even more powerful when combined with Ways.
