Saw something similar to this come across me on Standard lately.
Tried to recreate it and share this glorious fun deck!
Currently taking this for a climb from Gold 10 to Diamond2.
TOP Prio : Vanndar and Incanter's Flow
Second/Third prio : Primordial Studies and Biscuit.
Obviously Mulligan for Vanndar at the beggining, however due to Primordial Studies having a high chance for you to Discover Solarian, aim for that too, Solarian dying prio to turn 4 and you putting on Vann whilst Prime Solarian is in the deck nets you a potential early out(if facing aggro druid/pirate warr) or a surprise win condition in a Control match up.
Win Rate; Honestly its just about breaking 55 % for me for most of the day, took a break and got it upto 62 rating before I go to sleep. Its wildly succeptable to aggro, so don't expect it to be there for a consistent climb, however the feeling of just bamboozling your way through your whole deck in a turn is just spectacular.
