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)
