Replication Technique is a Rare card from the Commander 2021 set, carrying the catalog number 358 and set code C21. This blue Sorcery requires a mana cost of {4}{U} to cast and has a mana value of 5. Designed by artist Viko Menezes, the card features a normal layout typical of the release. The card’s primary mechanic centers on duplication. When cast, the Demonstrate keyword allows you to copy the spell, then choose an opponent to also create a copy. Players controlling these copies may select new targets for their respective instances. Additionally, the spell allows the caster to create a token that is a copy of a target permanent they control. This dual function of manipulating spell resolution and generating permanent tokens provides strategic options within the Magic: The Gathering Commander format. The card’s ability to interact with both the stack and the battlefield makes it a notable piece for builders focusing on blue strategies. Collectors often track this card by its set code C21 and its position as number 358 in the Commander 2021 checklist. The combination of the Demonstrate keyword and the token creation effect defines the card’s identity within the set. The card remains a distinct part of the 2021 Commander releases, recognized by its specific mana cost and unique rules text.
