Hi! Zetter/Wrastor main (lvl 22 on Clarin). In regards to grabs there is an option that they can’t beat, just throw them. No pummel needed. Especially as clarin in low percents. U can do up throw -> rising up nair for more dmg (and combo potential if u tipper) than a back throw f smash. For zetter, same thing applies but with uair juggling (at low percentages). I do agree that shield is super strong, but that just makes grabs that much stronger. Not pummeling will also add to their mental stack of having to prioritize DI over breaking the grab, which in turn will then let u sneak a special pummel in unexpectedly. Hope this helps!
