Alt history Westeros:

Balon's Rebellion ends with the conquest of the Iron Isles by House Lannister! Setting up their pentoshi-style governor's palace on the Great Wyk, the Lions refurbish the broken fleets of the Greyjoys, putting them to good purpose. To rule, they happily adopt the religion of the Drowned God, convincing Aeron Damphair to be their spokesperson, with the Doubting Septas and Practical Believers of house Lannister abandoning the faith of the seven to embrace the precept "that which is drowned may never die". Governor Lancel Lannister is Drowned and Reborn, but is dubbed the "Sealion" by mocking bards.

Joust

Great Wyk is the engine here, driving all the shagga combos.

Need defence? Untap Pentoshi Manor.
Need draw? Untap the Mander or LIV.
Need surprise characters? Untap Iron Wind, drop a practical believer into play and untap one of your holy characters as you do so.

This is part tempo deck, part power of faith finisher, but mostly its about having so many options that you have an answer for mosy situations.
