Skrelv's Hive #33

At the beginning of your upkeep, you lose 1 life and create a 1/1 colorless Phyrexian Mite artifact creature token with toxic 1 and "This token can't block." (Players dealt combat damage by it also get a poison counter.) Corrupted — As long as an opponent has three or more poison counters, creatures you control with toxic have lifelink.
