These are the cards you'll want to hang on to. This is definitely tentative on who you're up against, but its a good base.
Deck has been doing pretty well for me. Main idea is to survive until turn 9 (or a turn where you can use coins from Gilded Gargoyle to OTK your opponent with massive damage from Mind Blast and/or Holy Smite.
Zilliax is there to slow down aggro. Don’t be afraid to use your resurrect cards on him to keep yourself alive.
Overall, you are looking to have Prophet Velen and Malygos on the board at the same time to boost your damage spells significantly. This can be done with Zerek's Cloning Gallery or by using one of many resurrect resources.
You have mad ways to heal yourself with Malygos. Full heals can be done with Spirit Lash.
This deck is rather difficult to master (at least it was for me), as you’ll be making some tough decisions depending on what you are up against. Good luck!
