Hollow One The key card in a Modern archetype, Hollow One is powerful, not for its MTG Cycling ability, but because you can play it for a reduced cost
Features: Includes 30 Reality Fracture Play Boosters
It notably triggers when a card is milled, not when you/an opponent mills, so anything that just dumps everyone's graveyards is fantastic here
I feel like Faithless Looting is one of the best cards to have in your opening hand with this build

Thats the idea here, with Skullbriar stacking up counters as it moves in and out of the command zone or graveyard
