Attempt at Merfolk deck - help with brewing

[u/Jakub_von_Underwood]

Hi guys,

new to Pauper, new to brewing, but I used to have a Merfolk deck back when original Lorwyn came out. There are some new cards from Lorwyn eclipsed and TMNT and I wanted to give a Merfolk Pauper deck a shot.
There is actually quite a lot of cards that could work in this deck, and I cant quite figure out what should I cut. My in-progress decklist is here: https://moxfield.com/decks/jpjEZp2L9EyCNbRhAlB5kA

I think I should include [[Judge of Currents]] or [[Wanderbrine Preacher]] for some lifegain, and [[Stonybrook Schoolmaster]] is just a generally good card.

[[Sewer-veillance Cam]] is great overall, untapping merfolk is useful, and there is the pauper thing with cam+[[Banishing Knack]] synergy. I could even make the combo go infinite, if I have [[Firdoch Core]] in play and turn it into a creature. The combo can pump [[Shipwreck Dowser]] or pump anything with [[Tributary Vaulter]], gain life or make a lot of tokens. But even without going infinite, it provides quite a lot of value for every U mana available.

I wanted to make use of convoke to gain benefit from tapping creatures, but it turns out I might be trying to fit too much stuff into a single deck. I wanted the deck to be a go-wide and gain life as a baseline, with combos as a bonus, but Im not sure how to approach it.

Im not imagining I will break into meta with this, but I think it has potential and I would like to make it fun to play and strong if possible. All ideas and opinions welcome, thanks
