Overall Strategy

As any good zealot would, Gut ensures that sacrifices are made to grow her 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 tokens will be the last ones to be sacrificed 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.
