Top 3 is one of my favorite brawls, and this particular deck I've had more fun with than any other.

Relatively simple play style: wait until turn 3 (otherwise you won't have time to play all your secret passages because of the short turn timer), then play as many coins and cultists as you can, play secret passage, repeat until you play 7 cultists. Summon Highkeeper Ra and have the opponent concede.

Mulligan Secret Passage away, as you want as many in your deck when you start the train of Secret Passages.

Note: this will fail occasionally. It's not perfect. But it's still fun as all get out
