I threw this in the Google translator and this came up:
"jajajajaj my English is terrible ... just wondering what is the justification of having 4 copies of a single card in a deck ... considering you can only lose again and have a total of 9 for all the partners in a regular deck ?"
This is supposed to be a choke deck that relies on
Gandalf MoW's ability for
A Light in His Mind to counter the burdens Bilbo generates when moving. To get him asap, he's 4x in the deck. As there is much twilight denial, less shadow cards are played and the chances of losing a companion are lesser, too. So no need to go all out with 9 companions here.
Hope that answers your question.
FYI: that's the first and only time I'll answer to a non-english comment. If I can use the Google translator, so can everyone else.
