Idol of Oblivion is a great card advantage tool for token decks, but you can trade it in for the 10/10 Eldrazi token in a pinch
Conclusions What are the key takeaways from looking back at these evaluations from one year ago

Beyond those suggestions, it really depends on what you think the deck is lacking the most: Red Wraths: Blasphemous Act, Rolling Earthquake Flash: Vedalken Orrery, Winding Canyons Sac Outlets: Ashnod's Altar, Phyrexian Altar, High Market Removal: Swords to Plowshares, Path to Exile, Grasp of Fate, Council's Judgment Card Draw: Wheel of Fortune, Mind's Eye, Chandra, Flamecaller, Skullclamp Ramp: Solemn Simulacrum, Sol Ring, Chromatic Lantern, Coalition Relic, Chrome Mox, Mox Opal, Mox Diamond, Mana Crypt, Mana Vault Protection: Boros Charm, Avacyn, Archangel of Hope, Glory, Flagstones of Trokair Tutors: Enlightened Tutor, Weathered Wayfarer, Tithe, Idyllic Tutor, Land Tax, Stoneforge Mystic, Godo, Bandit Warlord, Expedition Map Stax: Winter Orb, Static Orb, Cataclysm, Armageddon, Ravages of War Anti-Control: Stranglehold, Grand Abolisher, Price of Glory, Homeward Path Lands: Clifftop Retreat, Rugged Prairie, Plateau, Sacred Foundry, Arid Mesa, Strip Mine, Wasteland, Mistveil Plains (lets you re-use cards with Sunforger) I don't often do this, but here's my take on a blinged out Archangel Avacyn, where money isn't an obstacle: We've got the White Value Package for card advantage / ramp / library manipulation, a Sunforger Package that can be re-used with Mistveil Plains, Mass Land Destruction once we're ahead on the board, and numerous combo combinations involving Adarkar Valkyrie, Kiki-Jiki, Mirror Breaker, and Ashnod's Altar

The full set is finally out and I've been pouring over it to figure out what cards are going to impact Standard
While Brainstorm is a fantastic card, this reprint is a bit of a dud in terms of value
