the one ring mtg card MTG's LotR Is Selling For Over $100 then draw a card for each burden counter on The One Ring. The Coveted 'One Ring' Card

Or it can just be some crazy Blood token thing

Endurance Endurance might not be the most exciting Incarnation of the cycle but it's still a very strong card in Commander, doubling as both graveyard hate and protection in the same card: use this to hose an opposing Graveyard deck at instant speed, perhaps in response to a reanimation spell, or use it to protect your own graveyard from Bojuka Bogs and whatnot

If my opponent scries to top with Serum Visions or a mulligan and the matchup has some key card I need to hit, I will wait for a turn

The fact that it actually gives you the option of Boggart Bog makes me strangely happy

Even players who control no creatures arent safe from its ability
