I went for a cheap cost and efficient deck here.
The Heals and Raw Damage let you easily keep pace while SOA and SOB help cover the nasty's.
You have a Pseudo Dr with Willow and solid stats for the most part.
As for Crunchy, I'm surprised at his effectiveness; he's good.
Up to 4 Pills against 7 Power Cards he will usually Tie (And win thanks to 2* status )
7 x 4 = 28. 28 - 12 = 16. 4 x 4 = 16
Great surprise to find this out !
I'd change a few things but for only 15k it looks like a nice deck
Tuck + Rico + Yookie + Flora = cheap, but one of the best Roots half decks in ELO. It will only cost you 1k more
Oshitsune is good but I think he is banned next week. Glorg is a replacement. Crunchy and Mawpin are ok cards, but I think Phyllis and Artus are more useful.
I don't like Magenta, but she is the best 4* Nightmare for 2k or cheaper. Maybe change her to Edwin and one of your 2* to Cutey/Crowen/Pan
Oshitsune/Glorg, Edwin, Pan, Cutey/Crowen (or Oshitsune, Glorg, Edwin, Artus/Phyllis)
Tuck, Yookie, Rico, Flora
Costs 5k more than your current deck but I think it's much more useful
I agree with almost everything you say DUC-San but I have one slight issue.
Magenta is the card in Nightmare who I've frequently clinched / won quite a few matches with.
Oshitsune gets banned all the time. Glorg is cool though. I often times try to use Betelgeuse to moderate sucess.
Eadh is actually ok for his price as well.
