If I use Tauros' "Destructive Horn" attack, flip heads, and discard the only {M} Energy attached to my opponent's Orthworm ex, does my Tauros take damage from the Orthworm ex's "Pummeling Payback" Ability or not?
Since there are no {M} Energy attached when the effect of Pummeling Payback is triggered, no damage counters are placed on Tauros.
