My primary cube - Defender of the Polyverse - has evolved to be much more efficient than it was originally.

This cube is a space where I can play all of the slower, more swingy, and more narrow / combo oriented cards without stressing as much about efficient interactive game play.

Expect:

• Comparatively limited removal to allow snowballing games.
• Relatively weak aggro to enable bigger decks to emerge.
• Less efficient mana fixing to save on $$ and hamstring aggro.

Who knows if this will be fun, but it's worth a shot.
