[This Way has the text of the played card but with “+ X cards” instead of “+ X $” and vice versa].
That seems like it would clarify how it
currently works (except that it's a bit inaccurate since only +cards and +$
this turn are supposed to be converted).
If you wanted to change how Chameleon works so that Lantern and Elder would still function, you need to change the current ruling on "follow its instructions".
Chameleon effectively says (incorporating the general rule of Ways):
"Instead of following the instructions of the played card, follow its instructions with these modifications..."And according to the current ruling, this counts as following Chameleon's instructions,
NOT the card's instructions. So Lantern and Elder don't do anything, since they only trigger as you are following the card's instructions.
So we would instead interpret Chameleon such that it counts as following the card's instructions:
"Instead of following the instructions of the played card, follow its instructions." <-- This means that we
ARE following the card's instructions after all.
"When it would give you +Cards this turn, you get +$ instead, and vice versa." <-- This means that Chameleon triggers as you are following the card's instructions, like Lantern/Elder.
However, this would also have other consequences:
* When under Enchantress attack, using Chameleon does not prevent Enchantress (unlike with other Ways).
* When playing Moat, you can choose to lose the -1 Card token, then convert the other +1 Card to +$1. (Currently, you get +$2 from Moat, and keep you -1 Card token.) Similarly with Militia and -$1 token.
