Artifact
Scars of Mirrodin
50/100
Plays about the same in 2HG as it does in any other format.
No 2HG-specific rules fire on this card — it plays much the same here as anywhere else.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
When this artifact enters, put a -1/-1 counter on each creature target player controls.
, 
: Proliferate twice. (Choose any number of permanents and/or players, then give each another counter of each kind already there. Then do it again.)
Fits the same colour identity — good candidates for your teammate's deck.
Suggestions are characteristic-based for now. Once teams submit pairings, this becomes a real co-occurrence score: played in X% of teams whose partner deck runs Contagion Engine.
