This enchantment exiles all cards from all graveyards upon entering the battlefield
There are no other options
This card would greatly benefit decks focused on token generation, +1/+1 counters, or planeswalker abilities, as it effectively doubles the impact of these strategies
You also had to worry about running into Icy Manipulator
It also had Basalt Monolith, a card that goes infinite with a ham sandwich, and Juggernaut, a card that isn't great by today's standards, but at the time it was one of the best Creatures in the game
Also, if you're thinking of any kindred strategy and/or commander you'd like to see featured, just write it in the comments as well
