Not much, but a few thoughts, enjoyed playing ya the other day!

• Increasing Ambition instead of Diabolic Tutor
• Consider Vesuva / Thespian's Stage and Myriad Landscape
• Ditching a signet for Arcane Signet
• Fervor ?

Urth_drgn219 Vicious Shadows is my control hate, it is a great tutor card if everyone has a scary board. I like Sarkhan Vol a lot and will get a copy eventually but I've used Xenagos, the Reveler in that role for a while and he works great. Im not the biggest fan of Vraska, Relic Seeker as she just ends up being awkward removal most games. I have Phyrexian Arena in other decks but I like Fecundity better in this deck. Eternal Witness is just a better Golgari Findbroker too. Thank you for the suggestions!

Dudeguy92man You're definitely right about Increasing Ambition , ideally it would be a Vampiric Tutor . Didn't realize Thespian's Stage was so cheap ill have to pick up a few copies. Arcane Signet is great, thanks for that one too. Fervor would be a good upgrade for Ogre Battledriver too. Hope to see you on untap again sometime!
