Kindle

Kindle is a slang term used by Magic R&D to describe the spells that look at the graveyard for other copies, getting increasingly stronger dependent on the number of those copies. First seen on the eponymous Kindle, the effect was designed by Mark Rosewater to be a non-creature version of Plague Rats. This design of card tends to appear at least once each time a cycle of common "collect them all" type cards are printed, such as in Magic Origins and Core Set 2020.
