Although this card has good effect, its versatility still does not surpass cards like Enemy Controller, Windstorm of Etaqua, Curse of Anubis, in terms of position switching cards, the primary reason is that these cards does not have the prerequisite of having a Machine-type monster on the field in order to activate.
If you are to include this card into your deck, it is recommended to put at most 2 copies to make room for other versatile alternatives.
This card can be activated during your opponent’s Main Phase or Battle Phase, strategically it is recommended to activate during their Battle Phase, first reason is to catch your opponent off guard, second reason is to prevent them from adjusting their strategy during their Main Phase.
The strength of this card compared to other position-switching cards is that, during that turn this card is activated, all your opponent’s existing monsters, and would-be Normal Summoned/Special Summoned monsters, will be forced into Defense mode, this potentially disrupt current meta decks, such as Red-Eyes decks, which can activate Red Eyes Spirit during Battle Phase to Special Summon another Red-Eyes monster for a follow up attack; and also Ninja decks, which has the potential to perform multiple attacks using their Transformation/Duplication traps during Battle Phase. All these Special Summoned monsters are forced into Defense mode until the end of the turn Pulse Mines was activated.
OR you can use Earthquake or Card Rotator or Enemy Controller with Tragedy. You won't have to have a machine monster on the field then. Preferable to use on 1-2 monsters (waiting until they have 3 is too risky)
Funny how a card used in Geargias is now "interesting" in ancient gears.
It's an insanely good Machine support. Obviously every Machine deck that doesn't require another Semi'd card will at least heavily consider this thing. It has nothing to do with Geargia players being geniuses.
this card does not activate during damage step, for anyone wondering
Yeah, I cucked my opponents OTK plays just with pulse mines. They kept on special summoning after their normal summon only to find their monsters being switched to defense mode each time.The retaliated with a hard rage quit.
When you Ritual Summon a monster, you can banish this card from your Graveyard as 1 of the monsters required for the Ritual Summon. The monster Ritual Summoned using this card is unaffected by Trap effects.
