I have tried decks for fun with this. Running all the 1 cost spells, then using it to refill the hand. Getting the 1 mana spell effects on the board can be handy. The really cool thing is that if you have 2 in your hand and you play them, you will begin to get x2 the cards off 1x spell, which can be fun if you have the coin.
As others have said, it is way too slow and basically a dead card for, what.. 80% of the game? It was fun while i was trying it out, even going as far as adding it to my dragon hunter control deck but obv that was a very slow deck.
