Yes, you can get them 2 ways…
Have the pets required for the support skill to activate, on your pet team.
Have the pet with the support skill on your team and have the other pets required on your team or at least evolved to 5-Stars off the team.
Pets that initiate the skill
Gummy, Furby, and Vega:
Targets have a 52% chance to reflect 7% damage when defending a normal attack.
Targets have a 73% chance to reflect 14% damage when defending a normal attack.
Each pet requires different pets to activate the skill with Twinkie being almost impossible to activate until you have opened a ton of pet chests, to get the two epic pets required.
Also, one of the epic pets has a reflect mutation skill but since they are so hard to evolve it’s doubtful to be seen or used.
