Goal of the deck:

Commander damage wins through damage doubling effects and some +1/+1 counter fun to surprise enemies. This deck is actually quite competitive and nearly always plays Reyhan, Last of the Abzan on turn three and then just finds ways for him to get through. The deck is very fast and does not like doing nothing for a turn so you want to mulligan to where you have a mana rock at least in your hand.

Key Cards:

Xenagos, God of Revels: This guy gives haste and +X/+X where X is target creatures power. Super Effective with double strike from Bruse Tarl, Boorish Herder on Reyhan, Last of the Abzan with 6 counters for a kill with commander damage

Iroas, God of Victory: Grants creatures menace and they do not take damage from the defender so spells and creatures opponents control are not threats

Gisela, Blade of Goldnight: Doubles all damage to opponents while halving damage to you and creatures you control. Pair this with Bruse Tarl, Boorish Herder + Xenagos, God of Revels, you gain 24 life and hit for 24 commander damage with a freshly played Reyhan, Last of the Abzan

Avacyn, Angel of Hope / Sigarda, Host of Herons: When you pop Defense of the Heart this is what you put down. It makes it much harder to get rid of your problem creatures with anything short of exile effects

Damage Doublers:

Gisela, Blade of Goldnight: Arguably the best one in the deck, she also halves damage coming at you and permanents you control

Xenagos, God of Revels: Doesn't quite double damage as much as double a creatures power and toughness

Wound Reflection: opponents take damage dealt to then again

Saskia the Unyielding: Makes an opponent take X damage, where X is combat damage your creatures deal (doubles the damage if you hit the chosen opponent but can also hit pillowforts)

Staple cards on field: Xenagos, God of Revels + Gisela, Blade of Goldnight + Reyhan, Last of the Abzan and then play Bruse Tarl, Boorish Herder to swing in for a minimum of 24 commander damage that is also lifelink. Have Iroas, God of Victory out and not even worry about blockers.

Almost any of the creatures can take the place of Reyhan to swing for massive amounts of damage

Saskia the Unyielding on battlefield; play Bruse Tarl, Boorish Herder to give her double strike and pump her one then cast Tainted Strike to kill two players in one swing
