A generic mid-range "flyer". I'm not sure; I feel at least one "flyer" should be U instead of UU, but also, islandwalk may be stronger than flying in a flood deck, so is 3U for 3/2 too good?

We could alternatively play with variants, eg. "If defending player controls a flooded land, ~ can be blocked only by blue creatures or creatures with flying" would be a lot, lot weaker but still have the flavour.

Flavor-wise, it may be difficult to explain why the flying creature can block a creature swimming through the water... but I suppose there's an answer to many things in flavor. I suppose the real strike against flyers blocking 'pseudo-islandwalkers' is that we're looking for mono to have answers to flyers, not the other way around. If anything, this creature should read "can't be blocked by flying creatures who's controller controls an island".

But I'm not sure that that's the best solution. It would be nice to have one straight-up french vanilla Islandwalker in the the 'Make everything an island' clan. If 3/2 is too good, I'd suggest changing the numbers so that it isn't too good anymore. 2/3, while underwhelming, would probably get the job done.

Lots (well several) of Birds hunt fish at sea by diving into the water to spear/grab/scoop up their prey and then take to the skies again so it isn't all that hard to imagine a Drake that does the same thing only with larger fish/merfolk/etc.

For flavour, I imagined the infiltrator would have to surface as some point, too far from land to be vulnerable to ground creatures, but enough to be vulnerable to flyers. But we definitely don't need to do it that way.

Maybe 2/2 for 2u? Still not Phantom Warrior but often better than Wind Drake.

Wild drake would be reasonable, but this should probably be sized and costed in conjunction with CU01 Serpent of the Endless Sea; one should probably be 2/2 (or slightly smaller) and one bigger than that. And then decide do they both have islandwalk, or does one have something else?

We also need a common for that cycle.

Well things just come together don't they.

2/2 for is Rootwater Commando. I quite like CU01 Serpent of the Endless Sea as is. I think we only want two islandwalkers at common, so I think we need to change one of this, CU01 Serpent of the Endless Sea or Serpent of the Endless Sea.

(Incidentally, the links that Jack and I are using are created by typing (((-CU01))).)

Good solid common. Efficient but burnable.
