I own both for Arcanists because of a couple old metal models I picked up that I liked better than the plastic versions. The generic upgrades are nice, but I do have one complaint.
I bought the Collodi starter today and plan on picking up the Neverborn Wave 2 deck so I can play him, but I want a few effigies to use as well. I don't think the effigies are going to be released before January so my only options are to buy the metal versions or wait 4+ months till the new versions come out. Ill most likely go for the metal versions, but I still need two cards that I can only get if I buy two faction decks that I only need a single card for.
I know there is the card trading forum, but man what a pain in the for a few cards.
