Soul Manipulation - I think better than Artful Takedown

Simic Cards- Pick 1 or 2, you only have 6 simic cards so one is free, the other you could swap out beetleform mage for.

Gruul Cards - I like both over Goblin Anarchomancer and Branching bolt potentially, really like Mauler a lot, was in my regular cube for a super long time.
