The effect's discard cost means this deck can't stay on the offensive forever, but your series of buffed attacks will cause your opponent's hand and Life to quickly evaporate
The deck rewards you for being fully colorless with powerful ramp engines like Forsaken Monument and Darksteel Monolith to cast big colorless haymakers like Kozilek, the Great Distortion and Rise of the Eldrazi
Ophidian was played at the kitchen table as a four-of and people would attack each other with agreements to "not block" so they could each draw cards from the other
So as long as the box is $50 or less, I say the scene boxes are worth it from a financial standpoint
The card enables a plethora of combos that can generate infinite mana, infinite creatures, infinite life gain, and the Urza player to cast their entire library
I also hope you've enjoyed my list and found it useful in finding the right adventure spells for your builds
