First strike
As long as it's your turn, creature tokens you control get +1/+0 and have first strike.
{W/P}: Create a 1/1 colorless Phyrexian Mite artifact creature token with toxic 1 and "This creature can't block." (Players dealt combat damage by it also get a poison counter. {W/P} can be paid with either or 2 life.)
