Theorycraft: Reliquary of Souls Galakrond (Ashes of Outland)

Disclaimer: all of the following is entirely theoretical to date. The author is a not a good player so take this with a pinch of salt.

The goal of the deck is to shuffle as many Reliquary Primes as possible into your deck and win using them.

Look for Reliquary of Souls, Embalming Ritual, Shadowy Figure, Wretched Reclaimer, Teron Gorefiend in your opening hand.

Hard counter: Rogue (Flik Skyshiv), Demon Hunter (Kayn Sunfury).

If you’re out of your Reliquary Primes, try to hold off with Galakrond. This deck has a lot of removal and “combo pieces” also work well with Convincing Infiltrators and Khartut Defenders.

Other cards which can be potentially included: Mass Resurrect (although only good with many Reliquary Primes, Convincing Infiltrators, and Khartut Defenders in the pool); Breath of the Infinite (against token/early game aggro decks); Madame Lazul, Thoughtseal etc. (additional resource generation) or some draw cards. If you’re feeling greedy, buff cards like Power Infusion.
