Bottomless Shifting Sand →Used Deck

At the time of its introduction, I thought, "Isn't it written that it's pretty strong that you can remove it every turn just by leaving it?"
During the opponent's end phase, the monster with the highest ATK on the field, including your own monster, will be destroyed by an effect that does not target. Since it is difficult to redeploy later with a normal Deck, if you do not put monsters on the field or set them, or if you use many monsters with low ATK, you will destroy the opponent's monsters in many situations. You can.
The troublesome thing is the self-destruct condition, and if you don't have 5 or more cards in your hand during your standby phase, you can't sustain and self-destruct.
Due to the nature of this card, it is most effective to open it during the opponent's end phase, but if you activate it in the first turn, unlike at that time, the current rule is that the normal draw of the draw phase is performed on the first turn of the first attack. Since you can't, unless you use some kind of Droso, if you don't set only this card and end it, the normal draw on the next turn will reduce your hand to 4 or less, and it will immediately self-destruct.
To use it as a single-use removal trap or a card for destroying your own monsters, the fact that the monsters that can be destroyed and the effect itself are too uncertain are not at all superior to the strength of penetrating the target resistance, and the actual battle would be difficult to use with
If there's one thing that's fortunate, it's that this self-destruction is caused by a card effect, so using a card like Imperial Custom can prevent it.

Comprehensive evaluation: You can use a monster with low ATK or bounce it, but it is difficult to use because there is only one monster per turn.
It's easy to create a situation where the opponent's end phase has a monster with the highest ATK on the opponent's field if you're on the defensive.
Regarding attacks, he can be eliminated by parrying attacks with Spell/Trap cards, monsters and tokens that cannot be destroyed in battle.
Even if you're not on the defensive, if you mainly bounce, you won't be destroyed, and you can avoid self-destruction, so it's a good matchup, and Spirit and Yosenju will self-bounce, so it's a good matchup.
However, since the countermeasures will be taken when the opponent finds out, Kana will not come for the second time.

There are a lot of things that are required to use it well, and it even comes to the point that it is slow to activate.
So far with this card, I'm wondering if spot removal really pays off.

Since the removal effect is activated every turn, it will be a rather troublesome card if you can maintain it. However, the problem is the danger of destroying monsters on your field and the strict maintenance conditions. The strictness of the maintenance conditions makes it easy to throw away the damage to yourself, but in reality, if you use it only once, there are many substitute cards, so you can use it in combination with 《Imperial Custom》or [ It would be better to put it into [Spirit] so that the effect can be applied multiple times.

A card that activates Hammer Shot at the end of each opponent's turn.
That said, it's hard to use this card unless it's his Deck, which saves your hand, and you should be aware that it can involve your own monsters as well.
A Spirit Deck that eliminates this disadvantage would be a very good removal card.

I have a feeling that end phase removal might be slow, but it's still an interesting removal source that breaks the opponent's defense.
The restrictions on the cards in your hand are a little strict, but you can think of it as being able to use the effect at least once.
However, if you want to use it, you want to use it many times.
It's not as good as Standard, but it's not bad to try it with Deck because he has a lot of cards in hand.

If you use it well, you can shoot removal every turn, so it's powerful, but the problem is its limitations.
It has a lot of cards in hand, and it goes well with spirits that return to the hand.
It may be possible to divide it into disposable and use.

Thank you for your help in the past.
Although there is a maintenance cost, it is possible to bury the opponent's powerful monster once.
Also, it doesn't stay on the field and returns to the hand, making it a good match with spirits that have many good cards.
However, if it's just a one-time removal, a normal free chain is fine, right? That's a taboo.

Being able to use removal effects every turn is powerful, but the limitations in the second half are painful.
But for the time being, the effect can be used once, so it's not impossible to use it in his Rock or Spirit Deck.
