If my opponent used Turtonator's "Shell Trap" attack and I have Espeon VMAX with the "Solar Revelation" Ability in play, will my Attacking Pokemon with energy attached receive the 8 damage counters from "Shell Trap" if I attack and do damage to Turtonator?
No, it will not receive the 8 damage counters. Solar Revelation prevents all effects of your opponent's attacks, and Shell Trap's damage counters are an effect of your opponent's attack.
