Handler has a lot of duds. Butterfly, Chameleon, Frog, Camel, Worm, Rat, and Turtle are all useless or mostly useless.
How are those duds?
If the set aside Ways are Chameleon, Sheep, and Squirrel, you can play it as Way of the Chameleon and then as one of the other two. So it essentially turns your three choices into four: Sheep, Squirrel, Chameleon'ed Sheep, and Chameleon'ed Squirrel.
Chameleon wouldn't cause the Way used by Handler to be affected.
Are you sure? Why not?
I had written up a whole post going into detail about why you couldn't use multiple of the set-aside ways at once last night, when I realized why Chameleon was different and you were right in the first place, so I just didn't post it. I'm guessing D782802859 has the same mix-up I did.
Because the set-aside ways aren't actually in the game in the same way that a normal way would be, you can't just use one of them any time you play an action. But with Chameleon, you are told to follow Handler's instructions, which involves choosing a set-aside way (again).
I would say Handler with Chameleon is actually far too messy to be really usable. If you choose Chameleon, and then choose Chameleon again, I guess that would just switch your
and cards back to how they were originally? Nothing stops you from choosing Chameleon forever... although I guess that the Menagerie rulebook also failed to stop you from choosing Mouse forever, and it was only a special ruling by Donald that said you can't do that.
*Edit* Now I re-read D782802859's comment and think that there's more to this... he wasn't mixed up int he same way I was. Chameleon only affects "each time that would give you..." The "that" in that sentence is "following this card's instructions". When you use a way, you aren't "following this card's instructions" anymore. As seen by
this long discussion. However, this depends on the specific intent behind how Handler's wording works... because it's using a wording that is different from normal ways. It says to "play this as" one of the set-aside ways. That's like old Band of Misfits wording, which would actually cause you to re-play the card.
I assumed however that the intent of Handler was to treat the set-aside ways just like a normal way in the game, meaning you can choose to follow their instructions instead of Handler's instructions. The whole "play this as a way" is weird and not quite sure what it means. A possible wording that makes it clearer and also removes the weird potential Chameleon interaction (making it weak with Chameleon):
Handler
Action -
+1 Card
+1 Action
--------------------------------------------------------
Setup: Set aside 3 Ways face up. These Ways are available to be used this game when you play Handler.
I'm guessing that this was the intended behavior of Handler.
