whenever you draw a card mtg Rules Text: proliferate, draw, card, 9 cards Any card that adds mana

decisions of an Artist (including not to perform for any reason)

Likely the right way to use it is to enchant the card itself with something you can get back when it dies and enchant a tokens it creates

There is a single deck with the Reality Fracture set, officially, focused on two themes: Tokens and warping

Because these cards arent at an especially high power level I expect the regular Magic Online offerings to eschew the mechanic entirely, and if you do want to incorporate dungeons into one of your Cubes I recommend going heavy on the mechanic so that players have good odds of actually completing one

Bring back something big with Disciple of Bolas to draw a bunch
