Hey Bartley! I dig the deck. it's a unique way to play magic! I see what you're saying about consistency, and the only thing that comes to mind is the quantity of big creatures. 16 seems like a lot, especially with Gambles. You could probably safely cut 4-6 of them, and run cantrips like
Manamorphose to help you dig for what you need for free. The
Bloodthorn Taunter in the maybeboard also seems like a good call as a way to get in right away and gives you another turn 2 play. It can also chump block if absolutely necessary.
Wheel of Fortune /
Wheel of Fate could be happy in this deck too to make sure you hit combo pieces.
I hope you found this helpful! Good Luck!
