Which version do you have?

For the absolute cheapest way to own Theoretical Duplication, grab the Standard version priced at $1. The Standard version at $2 offers no significant advantage over the $1 version; both are essentially the same card. Collectors prioritizing the lowest cost should stick to the $1 Standard. Those seeking a specific edition or packaging benefit from paying the extra dollar, but for pure card acquisition, the cheaper option suffices.
