A couple surprises.
The verdict is in and Ditto is guilty of disguising itself as these Pokemon in the 2020 Pokemon Trading Card Game Sword & Shield GO series:
Cards Ditto is Disguised As
|Common Reverse Holo 006/078 Spinarak||$5.19|
|Common Reverse Holo 013/078 Numel||$4.92|
|Common Reverse Holo 059/078 Bidoof||$6.12|
It was originally believed that Ditto only disguises itself as Bidoof. You can tell if the card can be peeled to reveal a Rare Holo 053/078 Ditto if there's a Ditto graphic on the bottom left of the card.
Interestingly, a Rare Holo 053/078 Ditto has been selling for $6.33.* Why not purchase the cheapest unpeeled version of the card and peel it yourself?
*The market value is the average price of what these cards are selling for as of this writing on TCG Player. This does not represent the cards future value.
