Combo is weak and uncommon, there is lots more removal floating around and a 2/2 will just trade badly with any number of similar dorks that have already obtained card advantage (Snapcaster, Trinket Mage etc) or sit on the sidelines and do nothing compared to actual threats people might make
Containment Priest completely shuts down Dredge, Oops and Reanimator strategies (when you come across them) and, frankly, has caused more immediate concessions than almost any other sideboard card
This card is playable in expanded format, making it highly sought after for players seeking M Rayquaza EXs powerful stats and ability to deal damage
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)
