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.

Silver heart[]

Cards from the Ponies: The Galloping set have a heart-shaped holofoil stamp.

Silver triangle[]

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.
