This is an Immortal Throne deck list. Its a semi MEME deck, that I would place in B tier fun deck against other fun decks, albeit on the harder side to pilot. The deck goes long, but can dish it out in mid game and survive agro with healing.

GAMEPLAN:

Try to get a Trade Encampment as fast as possible, swap a unique artifact for the Throne - be carefull to always have one in hand. Then place it in a corner while you are pathfinder, or on ordinary site if available. Try to play Throne on turn 5, then site to immediatly get off 1 draw. Next turn you go 1, 2, 3 ideally and draw 3. Card advantage alone can win you the game, but the MEME plan remains winning with sitting on the Throne.

As pathfinder you can cruise the realm, and when needed turn to Avatar of Air and teleport, move and blink to the Throne in one turn. Seer and Sorcerer are only needed if you lose Pathfinder mask, to cycle for cards you need.

Vampires and other life steal keeps you alive, movement (Displace, Avatar of Air, Wuthering heights) and trap sites kill enemies, Torshammer Trinkets let you trade up and heal more and proc Immortal throne when played.

Carrionette plays a big role in the deck, as it allows you to cast undead minions to stay in the game, especially the big undead monsters, and vampires. But it does not proc the Throne when it summons as the card is not cast (played). Also Deathspeaker and Book of the Dead let you cast from graves to proc Immortal Throne late game.

STARTING HAND:

Generaly you will want to mulligan and scry sites at the beginning, looking for Trade Encampment or Crossroads. If you don't get it yet, play with a unique artifact in hand should you Pathfinder into it. If you start your game with Trade Encampment in hand, mulligan searching for unique artefacts to swap for Immortal Throne. All Unique artefacts are fair game for swap and usable otherwise when throne is in game.

ALTERNATIVE GAMEPLAN:

If you miss the stall and Immortal throne gameplan you win by focusing on card draw, reanimating undead minions. Forgotten Tomb tries to discard an undead for Carionette plays Nightmare beeing the best as it is a 7 mana play for late game from grave. Updraft ridge is best played in back row, playing airborne minions (most of the deck) on them and threatening from back row where they are hard to remove and can sweep with torshammer trinket and Whirling blades. The deck without Throne plays somewhat as a birds/trap/reanimator list. If the game does not look like it will go long enough for Immortal Throne win lean heavy on this strategy and disregard the throne completely when necesary.

THREATS:

The main problem is Water with Atlantean Fate and Swap which are prime Feast for Crows (if played) targets right after Toolbox in other matchups, in Air Legion of Gall is a prime target. In Fire Redmane Hyena or Sinterfee. In Earth Earthquake and other stuff that burrows artefacts.
