ATK: 2300 / DEF: 0

That's one lazy lobster. I mean he doesn't even take the time to attack. Also, dat atk and incapability of staying in defense for long. He's like a straight upgrade to the "Goblin Attack Force" monsters. That being said, I can't really gauge how good he is. He can be special summoned which is nice and out side on effect negation he cant be changed to defense although............hmm "Level Limit - Area B" creates an infinite position switch loop with this. That's something to keep in mind.

 

Edit:More to review

Oh hey, it's Bujin Yamato
With regards to Level Limit Area-B, Guard Penalty lets you draw your whole deck.
You could swap the:

When this card is changed to Defense position: Change it to Attack position. If this card is face-up and in Defense position: Change it to face-up Attack position.

with something like:

This card's battle position cannot be changed, except by it's own effect. If this card is in Defense position: Change it to Attack position.

This way, it has a clause that clashes with Area-B and prevents said loops. Add to it, noting that it only works while face-up is rather redundant, since it's effect will only work if it IS face-up.

Effect aside... It's rather interesting idea in the sense that it's a battle-oriented 1-for-1-removal card, but has more pressure on the opponent because it forces them to be the one setting it off, rather then yourself.
The fact you can Xyz/Dweller/Masked Chameleon with it, is silly, and adds more versatility to it.

Edited the Defense to.... well, 50, so Masked Chameleon can't abuse him.  His purpose is one-for-one removal.  xP

Like, 1-2 Cloudians also have Masked Chameleon, and a few other random WATERs.
Nothing wrong with said card being an option for This.

Oh fine xD

I love this. This card is something I honestly think could be published and made into a real card. The weird effect, the funny art, and the name sell it for me. To avoid infinite loops maybe add something like "This card's battle position cannot be changed by the effects of Spell or Trap cards." That could avoid some headaches. If not I think either this or Level Limit area B could not be played (which ever would come second), like how other loops cannot be done.

His effect was updated so that he wouldn't be affected by Level Limit - Area B or other changing cards.  c:

It can't declare an attack and it dies if a monster suicides into it. If the suicide has 1400+ ATK, you will take more damage in the process. What is the point? Your opponent can build up scary boss monsters and then throw a random grunt at it.

 

Maybe some combo with a Command Knight-type monster that benefits from the presence of another monster on the field? I don't see a purpose.

[Lunar Origins]

Then what - should I just remove the damage clause?

[newhat]

I don't know what you intended this card to do. It just sits there waiting to hara-kiri.

[Lunar Origins]

That's the point.  It's a wall tempting your opponent to use their weaker combo pieces/xyzs to smash it down.
