Description[]
Silver oval[]
Silver oval holofoil stamps were introduced in the Magic 2015 set. This was done to make those cards feel more special, as well as to guarantee authenticity.[1] As such, it makes counterfeiting more difficult. Normal commons, uncommon cards, and basic lands do not feature this security stamp, except for basic lands from Unstable.
Gold oval[]
Cards from the Amonkhet Invocations set have a gold holofoil stamp.
Silver circle[]
Cards from the Signature Spellbook sets have circle-shaped holofoil stamps.
Silver heart[]
Cards from the Ponies: The Galloping set have a heart-shaped holofoil stamp.
Silver triangle[]
Non-canon cards feature a triangular holofoil stamp. These were intoduced in 2020.[2]
Silver acorn[]
Acorn security stamps were introduced in 2021 for Unfinity, to replace silver borders.[3] On common and uncommons the acorn stamp is printed on the card rather than embossed.
MTG Arena[]
