This looks more like a KrisDraw monster line with a Counter Fairy S/T line (not exactly but close). The KrisDraw deck should really have two goals (oddly enough neither one has anything to do with Kristya)
1. Put Thethys out as soon as possible and begin to get free cards
2. Use those free cards to Herald control your opponent
- 3 Magical Mallet
- 2 Book of Moon
- 2 Enemy Controller
- 3 Dark Birbe
There are way better cards than mallet for this deck, heck, even upstart can get the job done better. Plus, you don't really need the battle control that ECon and BoM provide, and bribe's slots can just be used better.
+ 3 Solidarity : All you monsters are Fairies and a 3200 Tethys is nothing to laugh at (or 1900 honests)
+ 2 Card Trader : It'll let you put back unneeded copies of Valhalla/Hecatrice back in your deck for fresh cards, plus it's a second draw everytime.
+ 3 Reckless Greed : Those two extra cards will keep you in the game alot of the time, back plus more draws for Tethys
+ 2 Beckoning Light : Kris set ups, Herald reloads, and Honest beats, need I say more
There's my two cents worth
