So, looking through my stock of Syndi cards again today...I came across "False Papers" - it's a 1-cost Steadfast Syndicate Attachment that says "Attach to a Character" - Exhaust False papers to give attached character a Subtype of your choice until the end of the phase.
Does this actually give them a new Subtype (entirely) - taking away their existing Subtype ? - or does it merely add an "extra" subtype to the character ?
--------------
Secondly, are there any cards in the game that out-and-out REMOVE Subtypes completely from a card ... ? My plan - if such exist - would be some kind of combo with Agency and / or Cthulhu - and being able to remove "Ancient One" - subtypes from those that have it - making them vulnerable to MANY of the games effects that normally cannot target / affect "Ancient One's" ... ?
