Red Reign →Used Deck

It works well with "Ascator, Dawnwalker", and after discarding this card for the cost over there, he can recover it from GY by playing a Dragon/DARK S monster.

Due to the nature of the effects of (1) and (2), I think that he is compatible with the "Red Archfiend" deck that fights with DARK, Dragon, and Synchro at high levels.
I think that the effect of (1) is excellent because if you use a high-level Synchro, you can banish other monsters and add strong effect resistance.
Even if you go to GY, the effect of (2) is that you can reuse it by using DARK / Dragon / Synchro, which I think is a strength.

crimson rain.
If there is an S monster of level 8 or higher on the field, remove all monsters other than the highest level monster on the field and give the remaining cards full effect resistance until the end of the turn, and a dark dragon S monster on the field Has the effect of being able to salvage from GY when is S summoned.
A very unique card that does not allow the existence of anything lower than itself and bury it, and furthermore, it does not allow trickery and brings it into a power match. The conditions are very heavy, but the benefits obtained are very large.
Since it excludes all monsters other than the highest level monster, it also excludes all Xs and Links that do not have a level, as well as the back side that cannot refer to the level. Since it can be used in a free chain, it can also be used for suppression. Thanks to the salvage effect, if you drop one GY, it will be reloaded every time you S Summon Darkness Dragon. With high level S monsters, he can be used in most decks, but if you combine the level and dark dragon parts, do you want to use it in Red Archfiend?
It can also grant removal resistance, but be careful that it is ineffective against chain removal. In the worst case, if a chain removal is introduced, it will leave monsters with effect resistance on the opponent's field, and this field may be destroyed.

The Jack Deck's resistance-enhancing card is finally out
The range to be granted is wide, and it is characterized by the wide range that excludes even the back defense of Link Xyz.
Since monsters of the same level are not excluded, Abyssberial's lineup will collapse, but the return associated with that will be large. In particular, if you target Calamity, who can give a big blow without letting your opponent do anything on the turn you play, you're almost guaranteed to win.

It has strong removal power and resistance to grant, and it has no demerits such as exclusion, which is rare for a self-recovery effect.
However, since your own army is relentlessly involved, it can be difficult to coordinate with other cards.
Also, be careful about chain removal. If you look closely at the effect that refers to the level of the field, it will also target the opponent's field, so in the worst case, only your field may be cleared.
It's a powerful but peculiar piece.
