Not sure about crushing hammer I just had 4 spare slots lol. Basically just trying to force them to stay in the active, because that's all you have to do to get the ko. Galar mine+abilitylock+tool jammer, tool jammer especially important because a lot of decks rely on float stones. That's also the reason for the field blower and megaton blower (megaton blower is underrated imo removing all special energies can ruin certain decks too). As usual I'm just making decks for fun nothing serious
