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

Oh, and for everyone whos going to claim that they fight that way because men will be distracted by their bodies *giggle*, end yourself
