These stand out immediately and are considered rare because they look like unfinished prototypes
As such, it lends itself very well to deck upgrades, but even if you forgo upgrading it, Limit Break is still a great deck to play with out of the box without any alterations
That said, white isnt the best color for discard, so it doesnt see much play
The deck is reliant on specific cards so I'm running a much higher than average amount of tutors: Trinket Mage to find our busted mana rocks, Tribute Mage to find Throne of Geth simply the best card in the 99, Solve the Equation and Mystical Teachings to find our poison cards, and Ringsight to find any black/blue card with Venser out, plus gives him skulk to get around blockers
The big difference between aftermath and flashback is that with aftermath, you get a different cardor to extend the above analogy, "draw" a different cardthan what you cast the first time
