Bladed Ambassador

A 3/1 for two in white is priced to trade up and die trying, and the oil counter here is the single-use insurance that lets it swing into a bigger blocker or through a sweeper and walk away once. That is the whole tension of the design: indestructible is a genuinely premium keyword, so it comes rationed to exactly one activation, and the mana tax on top means you pay for the privilege in the same combat step you spend it. Once the counter is gone, you are back to a fragile body that any point of damage answers. The counter is the more interesting piece than the protection it buys, because oil is a fungible resource in this Phyrexian design language: cards that add counters, move them, or proliferate them turn a one-shot shield into a repeatable one. On its own the ability reads as a modest hedge against removal and unfavorable blocks; inside a shell built to manufacture and multiply oil, the same line becomes a creature that shrugs off damage-based removal turn after turn. The body wants to attack, the counter wants a counters-matter engine around it, and the card sits at the seam between an aggressive two-drop and a proliferate payoff.
