I will grab The Visionary, Omnitron-X and, if Oaktree doesn't object, Chrono-Ranger. The time I've spent imagining possible villain decks I could put together is coming back to haunt me now...
EDIT: I get the feeling environment-building would just be cruel...
EDIT #2: Scrap that. Omnitron-X and Unity, please.
I'd like to give it a shot with Parse, Nightmist, Tachyon, and maybe Legacy, for a deck of discarding denial.
For Nightmist, I intend to give every card not from her deck a random spell value from 1 to 4 (avoiding duplicates of the same name), if that seems fair.
What is still available? If Unity and Chrono-Ranger are wanted already I guess I will start anew and just keep the Ra* deck on paper to be resurrected at some point if these challenges continue.
OK, I put something together:
Expatriette (character card)
Expatriette (10), Tempest (15), Ra (7), KNYFE (8) decks. Built another damager that can bring out some support and a few cards that can destroy on-going or environmental cards.
If someone wants to use one of these decks instead of me I might be able to shift into another deck. Though I would want to keep the Tempest deck since card draw capability is needed to some degree - and which I was using Chrono-ranger and Unity for in the last deck.
