As long as your deck runs heavy on draw and discard, you fill your graveyard up with expensive spells (or cheap ones simply by casting them), then once this big boy hits the battlefield, you can start reigning terror on your opponents by casting those big spells from beyond the grave for free
You get to play with some very powerful and cheap cards when you build around them
You can lean into this with a lifegain commander like Ayli, Eternal Pilgrim, Sorin of House Markov, or Karlov of the Ghost Council, and you can amplify your opponents life loss with effects like Wound Reflection and Warlock Class
Called the pity timer, every time you dont get a wildcard of any rarity when opening a pack, the drop rates for that rarity will increase
It's already a mini figure, a character for the D&D settings using Magic as reference, and a fan favorite
