I think Urza’s Saga is the strongest card in Modern. It’s a card that singlehandedly is keeping the Affinity archetype alive after the Mox Opal ban. It’s a card that can completely take over the game if unchecked.
Some months ago, I wrote a Deep Dive on Urza’s Saga and today, I want to show you the deck that exploits it best in Modern: UW Affinity. Affinity is well positioned in the metagame at the moment because it has a great matchup against UR Murktide and it has the tools to fight the cascade and Omnath decks.
