Like I mentioned above, this card shouldn't be used on its own often, but as a Basic Pokemon that has a Stage 1 evolution, this is certainly a solid one, with an average HP, and a move that both does damage and has the potential to inflict a Special Condition
As an additional benefit, if the card it draws into is a basic Fighting Energy, you are able to attach it to one of your Benched Pokmonproviding a small bit of acceleration
And it scales with the amount of players at a table, a hallmark of great Commander cards
Its a little difficult to keep track of which cards are in which pack, so we can not stress this enough use the aforementioned spreadsheet to help you narrow down which pack you should be opening
As a Basic Colourless Tera Pokemon, Terapagos can benefit from a lot of specific Abilities and effects such as the Sparkling Crystal ACE SPEC card or Bouffalants Curly Wall
