Ruby Yak OTK
With this deck I finished top 10 god rank this season, to counter everyone playing slow control decks (rakoan, treasure discover etc). Went 9:1 in the last climb with this deck (only losing once vs red rush). Usually finds turn 6 OTK even better than the "OP" Gagana OTK that got nerfed recently which found OTK only in turn 7. Ruby Yak is underrated by those who call it inconsistent, or I am just very lucky, because I find turn 6 OTK in 90% of the games I play. That being said, the deck was just made for fun and to surprise people. It loses to rush so not recommended for blind queuing on ladder.
How to play: keep cistern and lore thief on opening hand if you have them, or hard mulligan for fugoro/time of legends. (Only 2 draws in the deck for fugoro and 3 for everything else, meaning fugoro is the hardest piece of the puzzle to find). Play lore thief as collector and cisterns behind. Bank Faeria and draw your combo.
Combo: Ruby yak -> Failed Experiment -> Fugoro -> Rain of Fish -> Medallion -> Famine (Cost 21 Faeria, or 24 without failed experiment on fugoro)
Ruby yak is played first always, in case fish rain blocks your mountain!
Failed + stargazer is the best way to draw. Failed + lore thief is ok if you are desperate for draw. Try and keep 1 failed for fugoro unless you are sure you will have enough Faeria to do the combo without it. The 1 off plant can gain you an extra turn to draw your combo if you are getting pressured, but you can swap it out for more draw if you prefer.
Have fun! :)
