"Powersink Stone" Rating Score by みめっと

In other words, it's a kind of effect limiter-like permanent meta trap that isn't 《Summon Limit》.
After 2 counts, all monster effects on the field are shut down, and at the end of the turn, the counter is automatically removed and its binding force is reset, but the count itself is also performed by monster effects activated by hand or GY, and the count is applied to any monster effect, regardless of turn player or non-turn player.
Due to the above characteristics, if you use it in his deck, which has many monsters that can move even during the opponent's turn, it will be difficult for the opponent to deploy using activation effects and trigger effects, making it a rather unpleasant card.
Also, after removing counters in the End Phase, if there is a monster effect that can be activated in the End Phase of the turn, it can act until it counts down to 2 again, so it works well with Decks that can do that.
After removing a counter once in the End Phase, if a counter is put on this card again in the same End Phase, the counter must also be disposed of during the End Phase, but the timing is the same as the effect to be processed by yourself. or the other party, you can process them at any time until you give up the priority right to each other.
The End Phase is mandatory/optional, regardless of effect/cost, as long as you follow the priority, you can feel that it is a phase where you can process in any order.
