Part of my Blue Commons Submissions which will be up shortly.

upped cost and p/t to have this creature not compete with the other efficiently costed commons in the set.

Did this come up in playtest? Blue only occasionally gets two 4+ power sea monsters at common. I'm not sure what I'd suggest as -1/+1 seems an appropriate firebreathing for blue, and that requires a reasonably high power. At a minimum it should probably have defender?

You see all those "Edited Giant Hermit Crab"s up there. Each time I hit this card, I think I made it a touch better. It went from "Mercadian Masques Common", through our modern power levels, to, probably Magic 2017.

I don't know if we want to use Defender to solve all our problems. We do probably want more defender in the smaller creatures, since there's so much evasion in this set... but on the big creatures, it has a tendency to stop combat altogether.

Really, though, this could probably be okay as a 4/3 or 4/4. The dream of a giant Hermit Crab wrecking limited will be lost, but we already have Serpent of Endless Seas for that.

Yeah, it's easy to keep tweaking and get carried away. I'm trying not to overcompensate :)

I agree defender isn't a great answer, but I was just emphasising it as a sort of minimum standard... Reduced P/T for now. 4/3 is still fairly good for blue common, but more plausible. (Thinks to self We need to keep checking the skeleton to make sure we don't accidentally step on other card's toes when we change size.)

FWIW, Rachel says she thought the larger version of this card was very cute.
