Doppleganger + player help?
 

Can i use Doppleganger if someone is helping me?

Doppleganger is a duplicate, then i suppose than someone is helping me yet. But now i'm not sure about this, because it is only a potion, not a player.

The card says that you can only use it if you're fighting a Monster alone. So, if you have a helper, you can't use it, and if you use it and get a helper, you must discard it.

omg. Sorry, you are true, description said this. i was looking for because i remember that i had read it in some place, but i didn't thought that i had read this in card description.

In any case, i have learned a special rule in this post. and a new question please:
Can we discard a potion (or one use only items) and lose his bonus after we use?

Once you have played the card, it's not yours to discard anymore.
