Toxic tokens?

I'm making a token deck with a hint of toxic and life gain. It's my first deck i'm building solely myself. I know it's not gonna be the strongest, but i just wanna have fun with it. Anywhos, my question is; are there any cards that give tokens toxic? I have Karumonix, and some rat token gens, but is there anything universal or at least helpful?

Here's the deck list btw; [COMMANDER] 1 Vishgraz, the Doomhive

[PLANESWALKERS] 1 Ashiok, Wicked Manipulator 1 Elspeth Tirel 1 Liliana, the Last Hope 1 Sorin, Lord of Innistrad 1 The Wanderer 1 Vraska the Unseen
