Won a game with an older version of this and someone wanted to see my list so I figured I'd upload it.
The Solfachord is there because she's a fairy, so she lets Dimonno stay online if Angello gets sent to the ED and I can't get her back.
A lot of these cards are focused on protecting or retrieving Angello and Dimonno since they're what makes the deck work, and nothing in Vaalmonica itself actually lets you get copies back to hand from the ED... Performages were chosen because a lot of them deal small amounts of damage to you and they're spellcasters. Magicians are a new addition, but they're mainly here for Timestar's protection and the pend scale of 8 which gives some wiggle room with pend summons if Dimonno is destroyed.
