Hello Pokeaim. I have made a National Dex Regieleki team that (like most regieleki teams) uses its tools to wear down many common ground types in the tier. The difference with my team is that regieleki has z-hyper beam. I feel like it is a very fun and very strong team. If you have any other questions about the team just hit me up. https://pokepast.es/d395dbf0d6a35d92
With sucker punch ohkos the following
Darmanitan galar, cinderace, pheromosa, regileki, calyrex-shadow, dracovish (roll in their favor), and much more, it is mainly there to revenge threats though
Knock off ohkos most sets of necrozma dusk mane, it can ohko Kyogre, palkia, zekrom and many more threats it has an insane damage output
