Voltch Bicorn

By far, the best -Corn monster out there.

You can either abuse its mill effect to the graveyard, where you can re-abuse its milling through Wicked Reborn and Lost Star Descents.

Which is great, since you have pot of avarice to ensure your enemy decks out first!

OR

You can be really tricky and use Macro Cosmos/Dimension Fissure, and mill to the RFG.

And wow does that hurt.

Especailly since you run not three, but SIX D.D.R.s for our favorite Bicorn ;)
