Ya, G-Dos teching Bronzong would be awful. Same with ERL because a G-dos deck typically has Azelfs, Uxies, and sometimes Mespirts. I usually have 1/2 Uxies an Azelf, a Regice, and sometimes a Crobat G on my bench, leaving a Space for Combee. Using ERL would give your opponent 2-3 prizes, and 2 more next time. That could determine a game.
