Energy Card Question

[SamuraiMaster]

Can you use energy cards from an old set in a "modified" format tournament? (example: {W} energy from Jungle set)

 

[AronTrainer]

Yes because there is no wording on the card becides the back side Saying "POKEMON"

 

[Zyflair]

As long if your "outdated" card has a reprint in the current format, then you can use it.

In other words, yes.
