I also would not be surprised to see this card crop in U/R Phoenix as it will just get out of hand in any spell-dense deck
First, the champion, playing Mono-Black Necro Control: Creatures (7) Lands (23) Spells (30) 4 Nevinyrral's Disk 1 Hymn to Tourach 4 Necropotence 1 Ivory Tower 4 Dark Ritual 4 Drain Life 3 Stupor 2 Mind Warp 3 Contagion 1 Serrated Arrows 2 Demonic Consultation 1 Zuran Orb Sideboard Then, in third place, representing the aggro decks of the format, Brian Hackers Bad Moon Necro: Creatures (19) Lands (21) Spells (20) And then finally carrying on the fine tradition of B/r Necro-decks, Chris Pikula, who actually increased the red presence in the deck with Incinerates and multiple maindeck Shatters (Winter Orb, Howling Mine, Serrated Arrows, even Black Vise, Ivory Tower, and Zuran Orb were worthy targets)
For those of you not in the know, the Unknown Events are fun casual sealed events held mainly at MagicCons (and GenCon last year)
Unlimited cards changed this with a gray shadow effect and bolder text
