Infested Fleshcutter

Equipment that manufactures its own bodies solves the oldest liability with gear: the moment the equipped creature dies, the sword sits on the floor doing nothing. Here the buff and the token engine are stapled together, so every swing spawns a fresh Phyrexian Mite that puts a poison counter on any player it damages, and the +2/+0 keeps the carrier hitting hard enough to matter. The design leans on toxic to make the tokens more than chump-fodder speed bumps: each Mite that lands is a fraction of a poison kill accumulating on the side, independent of the main clock. The restraint lives in the pace of accrual (one Mite per attack at toxic 1) and in the fact that the tokens explicitly can't block, so they push the board forward rather than stabilizing it. That clause is doing real strategic work: this is an aggressive tool that punishes you for wanting to play defense with your own creations. The equip cost of is steep enough that moving it mid-game is rarely free, which pushes it toward planting it on one durable attacker and leaving it there. It belongs to the school of Equipment that treats the wearer as a launch platform rather than a champion, closer in spirit to token-generating gear than to a raw stat-stick like Bonesplitter.
