This is a take on a tron deck that combines aggressive turn three Karn Liberated, Mindslaver lock, and Polymorph.

The urza lands

The tron lands are three lands, Urza's Mine Urza's Tower and urza's powerplant . When you control all three of them they produce seven colorless mana. this can be handy for a turn three karn or a turn four Ugin, the Spirit Dragon.

Mindslaver

When you have 11 mana you can sac Mindslaver put on top with Academy Ruins and draw Mindslaver next turn.

Polymorph

During your opponent's turn cast Abstruse Interference or Warping Wail to get a scion token. Then on your turn Polymorph it into a Void Winnower.
