Magic: The Gathering

Lately I’ve been getting back into magic after a 3-4 year hiatus and have been building edh decks but have been struggling to find cuts to slim down my decks to 100 cards. Currently I’m rebuilding one of my all time favorites the locus god. Got it down to 108 cards then sleeved them all up and gold fished until I cut it down to 100 removing the cards that felt lack luster that seemed to work well. What are y’all’s favorite ways to make final cuts or find new cards?
