Sharkticon, Defector Mite

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
Skrelv, Defector Mite can’t block.

{p/c}, {t}: Choose a color. Another target creature you control gains toxic 1 and hexproof from that color until end of turn. It can’t be blocked by creatures of that color this turn. ({p/c} can be paid with either {w} or 2 life.)
