What is the point of making a token with a triggered ability that swaps? You just lose the token. I think a weakness of swap right now is that it actually sometimes wants to be just the second half of the swap and you have to use hacks like this to get it.

But swap is such a wordy ability that you cannot really afford complex long-winded hacks like this.

Have you considered just that? Start what the action means at "reveal" and call it something like "evoke", "scour" or "hunt". You could have a card with an ability that just says ": Hunt for Food." :)

That is very flavorful names actually.

the mechanic suggestion is also more efficient and better in lots of ways.

I'm going to keep calling it Swap because I like the pun in the title of the cardset.
