What would you recommend for mulligan?

I'll make a guide soon. this decks mulligan is kinda hard since you have many cards that can work very nice in conjunction with specific cards in your starting hand, such as VanCleef, Vendetta, etc.

But here's a short mulligan guide:

Usually I keep Pharaoh Cat, Flybooter, Zephrys and Swashburglar, no matter the matchup.

Against anything aggressive; keep Backstab, Seal Fate. (with coin you can also keep SI:7 Agent & EVIL Miscreant. I would not recommend keeping Apothecary since he's kinda slow against anything aggressive.)
Also, you can keep Vendetta if you have anything, that can trigger it's discount effect!

Against control, I would just try to get to Apothecary. Sap is also pretty nice against Warlocks since you can sap whatever comes out of their Voidcaller. With coin I would try to go for Elven Minstrel, Edwin VanCleef or EVIL Miscreant.

Hope this helps! :)

Yah, this is great. thank you

do i need to have patches:( im only missing him

he's not that necessary. just another nice that helps you gain tempo against more aggressive decks. also nice to thin out you deck.

you can actually tech-in whatever you want. something like Zilliax or Loatheb is also nice. 
also tried Cavern Shinyfinder to get the apothecary-combo more consistent, i just liked patches more! :)
