I'd say get rid of the Kraken's Eye and two of the islands and put in some of the really important cards in there that are only singletons. You might want to test run a 20 land deck first, but I think you shouldn't have too much problems since you barely even have any 4 mana cost cards.

I am proud to say that I own at least one version of every Merfolk cards ever printed. I emphasize the word, one. This is my secret shame. I want more of some cards, but I just never get around to buying them :.(.

The Kraken's Eye is a new edition to the deck. I wanted to see if it helped to stabilize the deck in that fateful hour (ha...ha...ha..ha...ha).

Pitching the two Island s is a good idea. I just have to figure out what to put in.

Put in some of the transmute cards. Look them up at gatherer, there are a lot of them and they will be VERY useful.

I would recommend putting cards with island walk or something...

Isn’t Puresight Merrow also an infinite combo with Paradise Mantle? It doesn’t win you the game, but I guess it helps you find cards you need. You could try that if you need more Merfolk based infinite combos.
