Dismiss into Dreams sounds like a great idea, but I'm not sure if I got enough creatures in deck to get full use out of it. But I'll keep it in mind.

Birthing Pod however is amazing. I will try to get one of them for the deck.

Further I will exchange Bramblecrush and Detention Sphere into it.

I was planing to get Supreme Verdict as well but didn't decide which card to cut for it, as I need a lot of removal to stay in later game.

Thanks for your advice!
