Good idea actually. The only reason why I didn't think of these was because the creature either has to be light or darkness, but not both.
Why not? Granted codeing might be a slight problem to get it to show up in more that one element when filtering.
Tho you can still make it a dual elemental card by making it absorb the second elemental type quanta upon entering play.
I.E. casting cost 4
(frist line of text on card) upon entering play asborb 4
This of course would be a one time absorb event.Would also make PU/TU have a hard time if the creature died right then if the absorb cost isn't paid.
Please note this is not ment to be an upkeep cost.
