(150 x 1.3 = 195) x 1.5 = idk something like 290. Porygon-Z's Adaptability Hyper Beam has 300 BP, so Gardevoir's is up there, but not the strongest. Unlike Porygon-Z's tho, it can hit things super effectively, so I'd say it's better overall. Not that one should ever consider using Hyper Beam on ha anyway, especially when she has 4mss in tha first place (Hyper Voice, Psyshock, Focus Blast, Thunderbolt, Shadow Ball, Energy Ball, etc.)
