My first submission here!
The intention here is make your void full of 2-cost-or-less units, both by
Tavrod, Auric Broker effect, or just dying in battle (in this case,
Xenan Cultist make them bigger). After that, make your
Memory Dredger put them back on board. The
Anointer of the Faithful interaction with paladin unit-type, helps with that.
The rest of deck is made, basically, with staples of Argenport. These deck was made with cards I have, and i'm still testing it. Having said that, I liked the results so far. But anything you think can improve it, just comment below.

Anyway, there are a few changes I would make to your deck.
First of all, you need more targets for Tavrods ability. You got the Minotaurs, but you should definitely play some more weapons. I recommend Inquisitor's Blade. Tavrod into Blade easily wins you the game. Alternatively you could try and squeeze some Bloodletter in.
Second: any - I can't stress that enough - ANY Argenport Midrange Deck needs to play Unseen Commando. It's strong enough on its own, but you also have Crownwatch Paladin and possibly Bloodletter.
Cut the Cultists, maybe two Favors and/or the Protects and add those cards.
Give it a try, I'm sure it'll work out better for you.
But I would still recommend switching Cultist for Blade.
