Iron Crown does beat other crowns if you don't get crit and is ev'd for haxorus and other mons that can sweep meowscarada and hands. Meowscarada is a regular adamant scarf set for scarf dragos, scarf hoopa or just regular hoopa, spectrier, and just is a reliable counter for other crowns. Iron hands beats val 80% of the time able to live one moonblast from counter encore and killing with play rough or you can supercell on turn 2 after using play rough turn 1 like normal and let them disable your play rough and then killing them with another supercell slam or close combat. It also beats specs darkrai and lives specs psychic too and it has 1 point in speed to outspeed other iron hands. This is just a simple team able to counter most meta mons.
