Does anyone know what creature is on this Magic card?

[eyebreaker7]

Maybe it's not one that's been done by WotC I don't know. Just curious if it has?

I believe it's of the merrow from Shadowmoor.

The sahuagin are basically the same concept.

Do you mean, what D&D creature does this look like?

Maybe a (Draconic) Kuo Toa?

The quote on the card is from a "merrow", which in 3.5 is an aquatic Ogre (http://www.d20srd.org/srd/monsters/ogre.htm#merrow).

[Troacctid]

It's a merrow.
