Overall Strategy

As a true zealot, Gut ensures that sacrifices are made to grow his skeletal army. It's best to sacrifice your opponent's creatures, but any will do.

Initial turns:
Turn 1-2: Play 1-2 mana value creatures/artifacts
Turn 3: Play Gut, True Soul Zealot. Sacrifice a creature/artifact and attack with a 4/1 skeleton with menace.
Turn 4: Play Inspiring Leader. Sacrifice another creature/artifact and attack with two 6/3 skeletons with menace.

The first few turns are spent creating skeletons and attacking ASAP. Later turns are for creating evasive attackers or clearing out blockers, thus all flying tokens are 3+ mana value. These token will be the last ones to sacrifice into skeletons.

>Individual Card Discussions

• Wrangle, Bloody Betrayal, Tentative Connection - Clear out a blocker, then sacrifice them to make more skeletons.
• Barrage of Boulders, Cosmotronic Wave - Clear out all blockers...and maybe even kill a few creatures along the way.
• Ancient Den, Great Furnace, Rustvale Bridge - Lands that can be sacrificed to make more skeletons if needed.

> Notable Exclusions

• Crib Swap, Afterlife, Reprobation - These all leave behind a blocker. And this deck is all agro, all the time.
• Dark-Dweller Oracle - Since we're trying to grow an army, the last thing we want to do is willingly give up creatures.
• Rukh Egg - While it would be awesome to sacrifice this for a skeleton, it's too slow. By the time we're at 4 mana (and not keeping mana up for a defense spell), the game should be nearly decided. Either Gut will be dealt with...or we'll be close to winning.
