Here's your design without the art - unfortunately, the type + subtype was slightly too long and runs into the rarity symbol. I have no option to change the size of the 'Type + Subtype' text, but I could fix this by simply removing "Lord" from the subtype.
However, I love the name - very nice, and I think that this card would work in gameplay. Shroud was made obsolete by Hexproof a couple years back (Hexproof does the same thing as Shroud, and Hexproof counters are a real thing), but I left Shroud on the card just for fun. I also changed the wording of the rules text slightly to conform to other cards more. The main change was adding "You control" to the Lord effect.
I feel like the only thing this card needs is some kind of activated or triggered ability, like an ETB ability, Dies Trigger, or something like:
{2}{u}{u}{t}: until end of turn, whenever a Kraken,
Leviathan, Octopus or Serpent you control deals combat damage to a player, you may draw a card.
Anyway, that's just an idea. I like the card! When I'm done with the Ooze Lord art, I can get a start on this one. Any specific way you want it to look?
