Cyn, The Mastermind

Menace, toxic 1 (Players dealt combat damage by this creature also get a poison counter.)

When Vishgraz, the Doomhive enters, create three 1/1 colorless Phyrexian Mite artifact creature tokens with toxic 1 and “This creature can’t block.”

Vishgraz gets +1/+1 for each poison counter your opponents have.
