For the Beheeyem set I have gone with SpD Nasty Plot which is a good blanket check for special attackers whilst also a good way for me to break Bulkier teams. Altaria was next because I wanted a good switch in to both Pawniard and Cacturne which can revenge kill Beheeyem pretty easily. Mawile gave me a good switch-in to Stoutland and a lot of other physical attackers that try to take advantage of Beheeyem's bad physical bulk. The next slot was originally Trapinch but after testing the team I realised I really needed another breaker and Golem can still benfit from Steel types being lured in by firing off powerful Earthquakes. Lumineon completed the core offering a water resist, defog and momentum to the team whilst I chose Dodrio as the last pokemon because it's a great revenge killer outspeeding most of the meta and benefits hugely from Steel Types being worn down.
