My first introduction to Modern was the mono-white Soul Sisters deck.
After some searching around, I discovered a variant using my new favorite card Norin the Wary.
This is my version of what I found.

Lots of ETB triggers with Soul Warden, Soul's Attendant, Auriok Champion, Champion of the Parish, Ajani's Pridemate, Genesis Chamber, and a mainboard Outpost Siege, which is a new addition over Purphoros, God of the Forge who has been moved to sideboard. Outpost Siege allows me to refill my hand when I've burned through my hand too quickly, or acts as a baby Purphoros, God of the Forge if I have a stronger board presence.

Legion Loyalist for when my opponents have been getting value out of Genesis Chamber.

Everything else is used to clear the way early: Path to Exile, Lightning Bolt, and Lightning Helix.

The sideboard is constantly fluctuating around, though Wear / Tear, Thalia, Guardian of Thraben, and Rest in Peace have been there since day one.
