Cast this spell only during combat on your turn and before blockers are declared. Create five 1/1 colorless Phyrexian Mite artifact creature tokens with toxic 1 and “This token can’t block.”. These tokens enter tapped and attacking target opponent. (Players dealt combat damage by a creature with toxic 1 also get a poison counter.) Overload {6}{w}{w}(You may cast this spell for its overload cost. If you do, change “target” in its text to “each.”)
