This is a Powerful Singleton Vintage Cube excluding a few cards that I find uninteresting, unfun or unworthy, namely:
• Un-cards
• The Initiative mechanic
• Minsc & Boo, Timeless Heroes
• True-Name Nemesis and Blightsteel Colossus
• Time Vault and Demonic Consultation

You'll find all of your typical Vintage Cube archetypes, but also pay attention to:
• The Lands Matter package with a Domain subtheme
• Rakdos Sacrifice/Aristocrat Combo
• Doomsday Combo

Note that the Splinter Twin combo package is now only half-supported with the removal of Kiki-Jiki, Mirror Breaker and a couple of its enablers.
