The Second Generation of Phyrexian Praetors (DMU, NEO, SNC, ONE) Urabrask, Heretic Praetor Jin-Gitaxias, Progress Tyrant Elesh Norn, Mother of Machines Vorinclex, Monstrous Raider Sheoldred, the Apocalypse The Phyrexian praetors have a good ability for you and deny a good ability from your opponent in a mirrored way (e.g.: buff your creatures, shrink theirs, double your counters, halve their counters)
Wear can destroy an artifact at instant speed, which is strong, but there are a lot of different decks that don't run any artifacts
Thatll give you at least three cards from your opponent's deck to work with, and let you cast those cards from exile for the entirety of the game
In fact, I often find I enjoy building decks almost as much as I enjoy playing the game
