Vorinclex, Voice of Hunger

The Praetor that turns the manabase into a weapon in both directions at once. Mana doubling for the controller is old green ground, but pairing it with an opponent-side tax (their lands stay tapped through a full untap step) is what makes this a true symmetry-breaker rather than a ramp engine. The asymmetry compounds: you cast from a doubled pool while every land your opponents spend lingers as dead weight, so a single attrition exchange across a couple of turns starves them out without a counterspell or removal cast. The denial half effectively works at instant speed, since the untap-step penalty fires whenever they tap, including in response on your turn, which means even reactive opponents pay the freeze. The 7/6 trample body is almost beside the point; the card has already decided the resource war before it swings. Of the five Phyrexian Praetors, this is the one aimed at the game's most fundamental shared resource rather than the stack or the board, a green control finisher wearing a beater's frame. Eight mana is the honest cost: neither half of the engine helps cast it, since both abilities require Vorinclex to already be on the battlefield, so you pay full freight up front with no discount from its own text. The design leans entirely on the mana-denial half to earn that slot.
