Riddle Cauldron

I recently played a game with Knucklebones, and got both a Feln Cauldron and a Riddle Game, which was quite the combo. This led to my attempt at "breaking" both cards, although I currently can't test this creation due to lack of shift stone.

This deck started as a Feln control deck where I replaced most of the win conditions with Feln Cauldron and Riddle Game. After that I've added time to get acces to Voice of the Speaker, Find the Way and Mystic Ascendant, which power up the Riddle Game without Feln Cauldron and generate cards to pitch to Feln Cauldron .

Cards I couldn't fit in, but did considere, are: Herald's Song, Whispering Wind, Gorgon Fanatic, Nocturnal Observer and Wisdom of the Elders.

In this deck Riddle Game should be able to generate over 12 cards
Battlefield: Voice of the Speaker, 1 Mystic Ascendant, 1 Feln Cauldron, 10 power,
You draw Find the Way (2), play both Find the Way (6), play a power, draw a power (8), draw from cauldron (13).
Or more realistically:
Battlefield: Voice of the Speaker, 1 Mystic Ascendant, 8 power.
Draw power (2), play Second Sight put back power (4), play power (6)

If some poor soul already opened 4 Riddle Games could he report if this idea works?
