Qebehsenuef, Protection of Horus →Used Deck

One of the four Horus related to "King's Sarcophagus", its duty is to strengthen the board surface by giving itself and other Horus resistance to battle destruction and target resistance.
The unique effects that other Horus have with common activation conditions are all effects that interfere with the field and GY, and effects that are related to some kind of numerical advantage, so naturally you want to get rid of the Horus you don't like the most. However, if you do that, the remaining Horus will be given two types of resistance, so the means to deal with the remaining Horus during that turn will be limited.
However, in the end, you can get rid of the first one, which you don't like the most, so there's little need to aim first.
I think this depends a lot on what effect your opponent uses to defeat the Horus monsters, specifically whether Imseti's effect is effective pressure.
Also, even if you make full use of the resistance given by the coffin, the resistance given by this card, and the common effects of the Horus monsters, you should be aware that cards like Air Foes and Barrier Wave can all be penetrated by a single card.

An effect that protects other Horus from being killed even if one Horus is defeated by some kind of targeted effect.
The biggest concern is that this card will be the first to be targeted if the opponent is trying to break through the target effect.
