Can I use traded Deltas and unofficial Megas in Purity Mode?

Well?

Can I?

I think the deltas and unoffial megas are still in purity mode, you only have to look for them.

Huh?

It said that somewhere, idk

Can I use both Purity Mode Charizard Y AND Delta Whatever?

not sure

What ARE you sure of?

k…

Yes, you can.
Purity mode just partially remove them from sight, but if you want to use them trading can be a possibility or you can just simply switch the purity mode off from options.
