Rank 4 Xyz - Double Agent Smog

[Valkyrus]

 

2 level 4 DARK monsters
Once per turn, you can detach 2 Xyz Materials from this card: switch control of this card and 1 monster your opponent controls. This card cannot be destroyed by battle. Double any battle damage you take from battles involving this card. If this card attacks or is attacked, it is changed to Defense Position at the end of the Battle Phase.

Hm, a Rank 4 Embodiment for DARK Decks. Well, it's a decent card, but I don't really see how this can be too helpful for DARK Decks, while they can run it, I doubt it's something people will go into often, unless the opponent has something amazing like Star Eater or something. The only problem I see with it is that it doesn't target, which I dislike on cards, since it always feels cheap to not know what my opponent is going to take, which sometimes is obvious, but still. Would it hurt it so badly if it targeted? That is always what I say when I make cards that don't target.

 

OCG fix:

Well, the effect is similar to Creature Swap, which does not target, so I don't see why it would be a problem if it doesn't as well. It's kind of an alternative to 101 in decks where you can make DARK Rank 4's, although when you take control of a monster you can use its effect too, which is something 101/Castel can't do. Also, if you take anything with over 2500 ATK you can deal some serious damage because when this is attacked the opponent will take double the damage. Furthermore, it can be attacked multiple times since it can't be destroyed by battle to inflict even more damage.

As a whole, it's a more situational, yet more devastating 101 alternative.

I was wondering whether to make it a generic Rank 4 but that seemed OP to me, or 3 mat, but then that seemed like a waste. Making it require LIGHT materials is pretty much the same as making it generic and WATER/FIRE/WIND/EARTH would be too specific. so I think DARK mats are enough of a nerf, but I'm open to suggestions on the materials/Type/Attribute
