"Dimension Wall" Rating Score by NeReiD

There is probably a card called Magic Cylinder that is most compared to this card.
The advantage of this card over Magic Cylinder is that it doesn't target opponent's monsters, so resistance can be ignored.
And although it is limited, there is a monster version of Magic Cylinder called Mahaama the Fairy Dragon, which can recover or burn that amount in response to battles damage.
This card deals "battles damage" when the opponent declares an attack, so when the opponent declares an attack with a monster with 4000 ATK → "Dimension Wall" is activated, dealing battles damage and dealing "Mahaama the Fairy Dragon" in response. His Special Summon deals damage. Thank you very much.
With a total of 8000, you can do a one-kill trick that Magic Cylinder cannot.
The advantage of "Magic Cylinder" is that it negates attacks, so you can protect your own monsters in battles between monsters.
Also, since it's effect damage, it's small, but you can add 300 damage with "Dark Room of Nightmare". In addition to this, it can be triggered when the opponent receives effect damage.
Like both cards, it's one of the best burn cards, depending on your opponent, but you can expect 2000-4000 damage per card. Since it is a card that cuts LP, it cannot take board advantage, so it is a card that takes LP advantage.
