This deck is built around Dune-Brood Nephilim as a General. Yes, I know using a Nephilim as a General isn't legal, but it's an amusing deck nevertheless.
This needs more ways to sneak lands into play, so the Dune-Brood gets more Sand when it hits.
There are some ways in the deck to give evasion to the Dune-Brood.
There are some sacrifice outlets and ways to tap the Sand tokens for effects in the deck.
