Relentless

Relentless is a slang term used by Magic R&D to describe spells that allow a constructed deck to have a larger number of copies of a certain-named card than the "four-of" Deckbuilding rule (100.2a) would normally allow. 
==Description==
This mechanic was first printed in black as a way to recapture the experience of playing under Richard Garfield's original Alpha rules, where there were no limits on the number of copies of a card a player could use in their deck. It is named after the first card to bare the mechanic, . While the majority of cards with relentless are black, The Council of Colors has deemed it available to any color as long as the flavor of the card is appropriate. Thus far, each Relentless card has a mechanic that magnifies the more copies that are played, making them Kindle variants.
A variant on the Relentless ability was created for Throne of Eldraine and introduced on the card . It allows players to break the "four-of" deckbuilding rule but places a higher maximum limit on the card seven, to match the flavor of the Seven Dwarfs. This restriction applies to both Limited and Constructed formats where the card is legal: for constructed this is an advantage. Still, this is a restriction for Limited as Limited decks could otherwise hypothetically play any number of copies. This variation would later be used to depict the nine Nazgûl in The Lord of the Rings: Tales of Middle-earth.
Strixhaven: School of Mages introduced the card , which is the first non-permanent to have the ability.
