I have two creatureless Merieke decklists, and this one represents what I actually have in my deck.  The other list was net-decked, then I added the subsequent Maybeboard of cards I would highly consider putting into it, pending what you have available.  This list will change as my deck changes and gets refined.

This deck needs a little explanation. It has a primary wincon goal of getting Proteus Staff and Goblin Charbelcher on the battlefield, and shooting our opponents for lethal with Charbelcher, one player each turn. Usually we'll use P.Staff to search for Charbelcher, so we only need the P.Staff to start, and hence many ways to search our library for it. First we use Proteus Staff to target Merieke (or a creature token or man-land we have in play), put her on the bottom of our library, then search for a creature, which will be her since we have no other creature cards in the deck. After we find her at the bottom (or don't find any creatures), we get to put each other card we looked at on the bottom of your library IN ANY ORDER. This is when you put Goblin Charbelcher on top, and all your lands on the bottom, right before Merieke. When you activate Charbelcher you go through all your nonland cards first, and then pop an opponent for that much damage. Rinse, and repeat the next turn. Each Charbelcher blast should do 40+ damage, if not 50+, as long as you get to it early enough in the game.  Unfortunately, since Charbelcher puts our nonland cards on the bottom of our library, in order to use it again we'll have to use Proteus Staff again to rearrange everything first, requiring 6cc each turn to pop an opponent in the face with them.

So while Charbelcher will be our lethal-damage wincon, it's actually part 2 of the master plan. The first part of that plan is getting infinite turns to use Charbelcher on. Luckily, Proteus Staff will be helping us do that too... above when I said we put Charbelcher on top, I lied... it'll be below Scroll Rack, Sword of the Meek, Thopter Foundry, and Time Sieve, which is our infinite turn combo, plus the likes of Sol Ring, Mana Crypt, and Mana Vault, which we'll be using to help cast the rest. Using our trusty Proteus Staff, we put the four infinite turn cards on top of our library, in that order, plus as many of Sol Ring, Mana Crypt, and Mana Vault that we need, pending how many cards we have in hand to swap with Scroll Rack. We draw Scroll Rack first, then swap our hand for the remaining five to seven cards, then cast our mana rocks, Time Sieve, Sword of the Meek, and Thopter Foundry. We use Sword of the Meek and Thopter Foundry together to get us five 1/1 artifact creature tokens for 5cc (after being cast), which can then be sacced to Time Sieve for an extra turn, then rinse and repeat the next turn, and mix in lethal blows from Charbelcher as soon as is feasible (if the infinite turns didn't cause everyone to scoop).

There is another option, too, being that we can put Necropetance first to be drawn (if we can afford the three black mana), followed by Scroll Rack, Promise of Power (puts cards in our hand, if needed, to swap using Scroll Rack), Mana Crypt, Mana Vault, Sol Ring, Gilded Lotus (and Chromatic Orrery, if we have the two extra mana needed to cast it, then Gilded Lotus), the lot of which we'll draw using Necropetance at the end of our turn, then cast them the following turn (Mana Crypt is free, and pays for Sol Ring and Mana Vault, which together pay for Gilded Lotus, or with two extra mana we cast Chromatic Orrery, then use that to cast Gilded Lotus).  We'll also put the following cards next in our rearranged deck, to be drawn/swapped into our hand with Scroll Rack ASAP: Goblin Charbelcher, Sword of the Meek, Thopter Foundry, and Time Sieve to get our infinite turns and damage wincons in hand, plus the likes of Dance of the Manse to recur any artifacts that should get removed (or put it higher in the order if we have artifact combo pieces in our graveyard already), followed by Sanguine Bond and Exquisite Blood, just in case yet another combo is needed (Dance of the Manse can grab those from the grave too).  Add in counterspells to the mix if you don't already have them in hand.

The rest of the deck is heavy control, anti-creature, generates token creatures, and is basically designed to stall out opponents. Merieke alone can create plenty of stalling, having the ability to steal attackers or blockers, and with untap mechanics, we can turn her into a creature killer as well.  Freed from the Reel, Pemmin's Aura, and Aura of Dominion each can turn Merieke into a mass murderer, with Aura of Dominion requiring the stealing of untapped creatures to fuel untapping Merieke and subsequently killing them.

Once opponents know how your deck functions, Proteus Staff will become their primary target for counterspells and removal, or one of the various infinite turn pieces we use.  I've tried to include enough recursion cards to help combat successful removal, and a bunch of counterspells to try and protect casting our combo pieces as well.  But it ain't easy once everyone knows you're ready to combo out at any given moment... my last run with this deck, I had three attempts at infinite combos thwarted, even though I had plenty of countermagic at my disposal, because everyone knew they all had to gang up and stop me or I'd win.  Alas, they succeeded... but barely.
