Mega Eevee abilities

My eevee has the ability Adaptability

If I mega evolve it, it gets protean maxima. So that means Mega Eevee loses adaptability? Because I wanted to use Trump Card on Mega Eevee, but without Adaptability, the damage isn’t too significant for the low PP of trump card

I’m pretty sure it does lose Adaptability.

Yeah, cause probably no one wants to use the normal form of Mega Eevee lol

I just thought that since Eevee gets Water Absorb if it transforms to Vaporeon, then if it transforms back to Eevee, it might have both Protean Maxima and Adaptability
