Let me know what y'all think!! I wanted to use the new god ephara... I think this is the perfect deck for her with all the creatures... And the added detention spheres I think will benefit...will def. come out of the gate a bit slower but might still be ok... The black kill spells in the sideboard is for the likes of mistcutter and the skylasher that has been very popular lately... At least at my lgs when I'm playing mono blue... They're face when u side in a black kill spell to deal with mistcutter is priceless... I'd love to hear any other suggestions or ideas you guys come up with... Thanks a lot!

What I did notice in this build is she gives amazing late game... With her 2 devotion symbols if her and thassa r on the field inactive at the same time it costs the same amount to turn her and thassa on together! Super sick when you're sitting on a nightveil late game like u should be for board wipes... And with all the small casting creatures im able to still apply steady pressure leading up to her... Was very smooth in testing, but we shall see!!
