Nah, I wasn't playing back then. Your examples make sense, but I still think it's strange to see a mono-white merfolk.
Been brewing this morning. Here's a loose Modern sketch that's probably not good but might be casually fun.
Edit: new list below
The idea of the deck, if it's not obvious, is to exploit cheap creatures that provide value when dead. Wrath a board with a bunch of your dudes? Profit. Rally on their turn for 1 or 2, block a bunch of stuff, Viscera Seer the rest away? Profit. Get that Grim Haruspex or Ascendency out, too? That's just gravy.
This is by no means a tuned list. There's no mainboard targeted removal, which you probably need (especially with Twin always around). It's obviously weak to Rest in Peace so it would need enchantment hate in the board.
Edit:
I forgot about Blood Artist! Here's an updated list
