This card works well in a Morphtronic or Karakuri deck because of their ability to Synchro Summon level-7 monsters with Morphtronic Scopen and Karakuri Komachi mdl 224 “Ninishi” respectively. Additionally they are both Machine decks so you can sometimes pull off Samurai Destroyer’s floating effect.
Aside from that, any deck capable of making level-7 Synchros can use Samurai Destroyer as an Extra Deck toolbox.
Lots of monsters are able to prevent your opponent from activating some card effects during the battle, most notably the Ancient Gear archetype. Samurai destroy and the cards listed below are able to prevent your opponent from activating all card effects during battle.
Star Eater has a different approach to this. Instead of preventing your opponent from activating card effects, it makes itself immune to all card effects.
