Sever the Skyline

This is a midrange deck that plays Endangered Qirin, Sindain's Bracers, and Sindain, Arcanum Curator to reach 7 or 8 power quickly and plays Unleash cards to gain advantage with that extra power. Striding Skyline sacrifices relics to cast more copies of itself and usually wins the game. The first Skyline can sacrifice one Xultan Eldermark to play a second Skyline instead of letting it draw a card. Valles Rex's cost is reduced by the discarded Unleash copy of Dunehill Clan and Striding Skyline, making it typically cost less than 8 power.

I initially built this deck as a Praxis cards deck but the Grumbo, Tota Legend + swarm strategy conflicted with the Striding Skyline + relics strategy too often, indicating to me that there are two Praxis decks in the format. Arcanum Orb is a valid replacement for Sindain's Bracers, and I included the Orb before recognizing that the Bracers would enable faster Skyline plays. I think the weakest card in the deck is Hour of Shavka, and the strongest card is Sindain, Arcanum Curator. Alhed, Mount Breaker is something to consider because of how it interacts with Unleash units and increases the number of Heroes in the deck.
