I assume basically all Human tribal decks will play a copy, and other Orzhov decks might considering running it as well, although there is a lot of competition since Swords to Plowshares, Path to Exile, Anguished Unmaking, Utter End, and Council's Judgment (among other exile-based removal spells) all see play in the format
Venser plays perfectly into the many White and Blue creatures that have abilities when they hit, like Thieving Magpie, Blinding Angel and #7 above
So, if a card with craft requires an artifact on the battlefield to be exiled, it can be a token, such as a Treasure
Vivien Reid Just like with Sarkhan, Fireblood, Im also high on Vivien Reid and believe its being overlooked by many right now
