I've had Shared Trauma for a while in my Oona Mill EDH. The problem is that no one else pays into it and I just end up tapping out to mill everybody 6 or something. There are better cards you an put in there

Thanks for your input allyourlives. That's it, I've been on the fence about Shared Trauma the past week or so but with that opinion, I'm going to replace it with Mesmeric Orb .

More easily tutored (thanks Tezzeret!) and more impactful for a mere 2 mana. I know my local card shop has some in stock for 1 so I'll replace it tomorrow.

Cool! Hey, do you mind helping me out with something? My EDH is here but I have trouble building a good board state with it to prevent creature-based decks from running over me. Any ideas? Every time I play something good, it gets countered and then people start gunning for me...
