Screen cap me! Galarian Weezing's secret second ability will be Misty Surge, and it's secret because it would tell us too much about the upcoming meta. Yep, terrain abilities will be more widespread among regular Pokemon come Gen 8. And we already know that Dynamax moves cause weather AND terrain effects. So after Weather Wars 1 (gen 5) and Weather Wars 2 (ORAS), and after a season of Terrain Wars (Gen 7), get ready for WEATHER PLUS TERRAIN WARS (turned up to eleven)!!
You thought Dynamaxing will NOT properly replace or be a fusion of mega evolution and z moves? You were right! It's just a glorified new tool to set up or change weather and terrain!
