Initially, I had
Dark Dweller Oracle, but WoodpeckerFM's comment made me consider
Experimental Frenzy, which does more of what I hope to do with the spot in the deck. As this deck is clearly very aggressive I feel like running out of creatures too quick could be
dangerous, so having a card that allows me to access more of my deck while I
rebuild a hand if I reach a later stage in my game could help me get out more goblins quicker. It is a little more of a
contingency plan, so I only ran two copies, but I feel that it could even help if you are doing well.
