If I draft Stoneforge Mystic in a given cube, Ill want powerful equipment to go alongside it, and if the cube is too large, the equipment might not even make it into the Draft packs
I can definitely understand people not putting Yawgmoth, Thran Physician in their top five list as its only played in one deck, which isnt a dominant player in the metagame either, but the card makes the archetype and there arent too many good mono-black creatures in Modern right now
At the top of your turn, you remove a time counter and once theyre all gone, you can cast that spell for free
Your gain comes at their loss
It had loyal fans and ardent foes
Or maybe something you don't mind getting back with a Scrap Mastery or Trash for Treasure
