>>38136454Strong Energy is what we call a "design black hole"
It forces everything there on Fighting-related to be balanced around it, rather than existing as a card to assist the type. It was like Yveltal-EX for Dark and Forest of Giant Plants for Grass where for multiple sets after cards of that type were intentionally made weaker knowing that if they were scaled identically to everything else they would be clearly overpowered.
If you need evidence just look through the following sets - Fighting types suddenly dry up in both quality and quantity, with Primal Groudon-EX not even needing Strong Energy in most cases and this Gigalith and Mamoswine (Breakthrough) being the most notable examples of even cards in the holo rare slot being deliberately undertuned due to Strong Energy.
