The Glitch Field makes normal type moves like Pyroar's Echoed Voice do physical damage instead of special. That means that Echoed Voice would be boosted by Adamant, and its damage would ramp up as its used and get increasing buffs from Moxie's atk boost-on-kill, Metronome's boost to moves used consecutively, and simply from the move itself as its used repeatedly. Her Pallosand, the only mon that would be capable to blocking this attack, is holding a seed which means its no longer ghost type. The only assistance Pyroar received from me was an Oricorio using Agility and Weakness Policy to Baton Pass +2/+2 in atk and speed.
