One of the fundamental ideas in the game is card abilities can actually alter the rules of play, allowing players to do things that are not normally expected
The Infinite Gyre, on other hand, destroys a single permanent when cast along with forcing your opponent to sacrifice four permanents whenever it attacks them
Not only do your equipped creatures have the ability to tap a defending creature when they attack, but when Nazahn enters the battlefield, you get to search your library for Hammer of Nazahn
So you could build an Oops, All Creatures deck and basically start with an opening hand of 7 cards plus Frodo, Adventurous Hobbit, Sam, Loyal Attendant, and Umori, the Collector
(Removing lore counters doesn't cause chapter abilities to trigger.) Put a lore counter on target Saga you control
The Cid card for this game is an artificer, a theme which continues throughout, and you can also celebrate Guy and his beavers before facing Yawgmoth
