Here's some new hotness: Excava, the Risen Past, a new option for a Horse commander (which, admittedly, does not care about Horses at all) that can reanimate any conventional permanent artifact, creature, or non-Aura enchantment in the form of a 1/1 flying Spirit token Naktamun Lorespinner, which becomes prepared when a player has one or fewer cards in their hand during your upkeep, allowing you to cast Wheel of Fortune (the last of the Reserved List entries in the cycle) to refill everyone's hands Advanced Reconstruction, another new Class enchantment that supports cast-from-exile or cast-from-top decks Relic Retriever, which I believe may have legs as a new format all-star at Bracket 4 power levels when it starts to make multiple Treasure tokens each turn cycle Turbulent Steppe, the expected white-red entry in the Turbulent lands cycle If there was no Land Tax in Silverquill, Lorehold Spirit would have taken the prize for best precon of the cycle in my eyes
