Trespassing Souleater

Phyrexian mana turned evasion into a colorless tax, and that trade is the whole reason this construct exists. The 2/2 body is irrelevant; it is a chassis whose only real job is to connect, so whatever you bolt on lands: equipment, poison counters, an aura that converts one swing into a clock, a combat-trigger you need to fire. The unblockable activation reads , which means a blue deck spends a blue mana and a non-blue deck spends two life, and either way the cost recurs every turn you want the swing to get through. That is the structural honesty of the card: a deck that leans on it each turn bleeds itself two life at a time, paying a rate against the very aggression it is trying to project, so the unblockable guarantee is never quite free. Several artifacts from this design wave used Phyrexian mana the same way, smuggling a colored effect into decks whose manabase could never support the color outright. Among that handful, this one trades raw power for the plainest mission statement: get something through, turn after turn, for a price you can always afford even when you cannot cast a blue spell.
