I'm slightly concerned about the flavor implications of this card, though I know that might seem a little pedantic.

We've never, even in the original set, laid out the overall geography of Archester. There is the overall "19th Century America"-Vibe that is obviously present from eastern cities, barren arid west, and fruitful wilderness over a mountain range, but we've never really commented on the coasts.

Presumably sea-based ships predated Airships, and humanity has never been afraid to sail into the unknown, so why did explorers only start exploring the western reaches of Archester with the advent of Airships? They should have been exploring it much earlier by sea, if they could get to it, so why couldn't they?

One idea I have is that, riffing off the 19th century again, there are (or were) a lot of really big, really mean, sea serpents. Perhaps they were even hunted for their fats like whales in our world were but having seen their depletion beginning to affect his people, the prophet invented Mana Steam as a susitute, not realizing the long-term effects it would have on archester' as environment.

Alternativemy, perhaps there are really treacherous seas all long the coasts, precluding sea-based travel to any great extent.

P.S. I have similar concerns about Everglades, we don't have a mention of natural swamps or marshes in our world building.

I don't think there should be any big sea creatures on whatever continent we are exploring. I think a giant lake would suffice. That would also make water (and steam) more valuable.

For the swamps, anything that's industrial waste could work. It doesn't have to be a literal swamp... a factory belching smoke, a contaminated grove, or a landfill could all fulfill the idea of a swamp.

My point was that both Everglades and Coral Atoll are somewhat problematic name-wise. It likely won't matter anyway since we were discussing the idea of updated Karoos with the Ravnica Bounce Land wording.

I for one always saw Archester having a coast line similar to that of the continental US. However I agree that we'll almost certainly be changing these if we end up using them.

As far as this card is concerned, I feel like this card's art would be a "joke" if you want. Like a far shot from a distance, showing an artificial Atoll, kept correct by humanoids.
