Oblivion stone, by default, is designed to indiscriminately destroy ALL non-land permanents in the game: yours, your enemies’, and your allies’. However, every turn, you can put a “fate counter” on a permanent to save it from being destroyed by this artifact. It works somewhat like Nevinyrral’s Disk except you have an option to “save” selected permanents from destruction when you activate this artifact.
Oblivion stone costs 3 colorless mana to play and can be tapped and sacrificed for 5 mana to destroy ALL permanents with no fate counters on them. To add a fate counter, to a permanent, just pay 4 mana and tap the artifact. In general, you can expect to add 1 counter to 1 permanent each turn unless of course you’re using an Icy Manipulator or similar card to untap the Oblivion Stone.
Watch me play with the Oblivion Stone
I didn’t have any fate counters on my permanents when I activated my stone in this game. I probably could have used a Nevinyrral’s Disk for less mana but I’m just demonstrating this particular card here.
Biorhythm is a Green Sorcery that changes every player’s life total to the # of creatures they control. If you use Oblivion Stone and place a fate counter on one or more of your creatures before playing the 2nd ability and then playing Biorhythm, you will win because you will have creatures while your opponent will have 0 and thus his/her life total becomes 0.
This artifact costs quite a bit of mana to use so it’s more useful in longer games. Plus, you’d want to designate a few of your permanents that you’ve worked so hard to play from the destruction you’re planning once you sacrifice the stone.
