Main point in this deck is to generate a lot of coins and razorpetals to combo with your Biteweeds, Edwin VanCleef and Malygos.
Lorewalker Cho is to gain enemies spells (duh.) or fill your opponents hand with coins to deny their card draw.
You can use coins to buff your Biteweed and Edwin VanCleef or play Malygos at turn 9, coin, sinister strike, coin, razorpetal and so on.
The Curator is to draw your Malygos.
This is obviously a tough combo to pull off so if you want a %100 win rate I do not recommend you to play this deck. But when you pull it off, it's really fun.
Enjoy and have fun.
