Remember when we complained about Maru not having access to a good Steel stab? That got me thinking: Brave, min Spe + Iron Ball gives it 88 Spe, so it can finally click Gyro Ball against max Spe base 80s and higher (otherwise, Zing Zap is still stronger). And Iron Ball means TR, so add in other TR mons like that one Clamperl Emvee used and Z-Draco Alolan Exeggutor.
