How it works
Declare Aurelia and Seluma as attackers. Aurelia triggers, causing you to untap all creatures you control and to get an additional combat phase after this one.
Activate Woe Strider by sacrificing Aurelia.
Deal combat damage using Seluma. Seluma triggers, returning Aurelia from your graveyard to the battlefield.
Repeat.
This looping assault relies on Seluma, Light of Aysen's combat damage trigger to continuously pull Aurelia, the Warleader out of the graveyard and right back onto the battlefield. Woe Strider acts as the sacrificial engine that puts Aurelia into the graveyard in the first place, while also providing fodder or smoothing your draws with its scry ability. Because Aurelia's attack trigger untaps your board and grants an extra combat phase every time she charges in for the first time each turn, you can repeat this cycle endlessly to generate infinite combat steps and damage.
