Actually, those are Cabal Rituals. Different Card.
And that's what I'm really worried about. The deck is extremely consistent, but aside from Force, it runs basically no disruption. Are there any clear ways to insert, say, Duress into the deck without destroying the main engine of Personal Tutor+Desire?
No. Blue is going to out-counter the snot out of this and shops are just going to lock it out insanely fast with only force to stop their first play and you haveing 3-4-6 as a majority of cc in your deck. If they land a single sphere, it is bad news for you.
