The first thing that came to mind when I saw the name was the Smoke Monster from Lost. Anywho:

 

An effect that helps put it in DEF with 2400 DEF, which may seem to push it. But I have seen other monsters with this much DEF (if not more) that did more, so it seems fair. With it face-up on the field, you have less worry of losing your backrow, so Solemn Notice stays safe. It's a nice protection, but the card's not impenetrable, so it seems fair.

Usually, Level 4 or lower monsters with a DEF past around 2200 (example of 2200 DEF: Gear Golem the Moving Fortress), would need an effect that's more of a drawback (Big Shield Gardna's 2600 DEF forces itself to Attack Position after being attacked, or Destiny HERO Defender makes your opponent draw 2 cards per turn for being there with its 2700 DEF, etc).

 

However, in this day and age, I think it is merely an outdated standard. We commonly see Monarchs with a 2400 DEF monster coming out of the Graveyard every turn, and the ATK of monsters is often from 2400 to 3000+ depending on what decks you see around, plus removal effects.

 

So I personally think 2400 DEF is ok. It breaks the mold, but I like that it does.

 

The attack lock it creates in multiples is cute too.

 

As for my suggestions.

The position changing effect I think should be a "you can" effect. I mean, what if I want it in Attack Position because I have Shield & Sword or Inverse Universe about to activate? It'd be fine being an option.

However, I think its protection effect, which is its main thing, can be a problem. It is a continuous effect so you could set a full line of backrow and Call of the Haunted into this card would protect a bit too much. I'm not sure I'm a fan of that.

I really like that same effect when it comes to protecting face-down monsters though, that side of its potential use would be creative....
