What is mtg token doublers?

MTG token doublers are cards or effects that create a copy of any token created by the player, effectively doubling the number of tokens generated. These doublers can be artifacts like Anointed Procession or creatures like Parallel Lives. Some of them also have additional effects, such as Rhys the Redeemed, whose token-doubling ability also allows players to choose whether to create Elf Warrior tokens or Saproling tokens. Doublers can be a valuable asset in creature-heavy decks that rely on token generation to quickly overwhelm opponents. However, they can also be vulnerable to removal spells or other effects that target artifacts or creatures.
