Esper Delver seems pretty sweet! Some Glacial Fortress/Drowned Catacomb might be nice to help smooth out the mana, and a couple Ghost Quarter might be useful. Lingering Souls also seems like something you should consider, even if it were for the SB.

For the SB, the following might be nice -

• Duress
• Negate
• Celestial Purge
• Dispel
• Spell Pierce
• Stony Silence

Good luck with the deck :)

id toss the orzhov charms for more hand control

Why? Orzhov Charm is amazing:)

ive just never liked it

Kills shit, saves shit, brings back Delver, what's not to like? Lol.

to me the removal on its over costed returning a 1 cmc monster to play isnt that good but i do like that you can get delver but hes your only target for that and if you want a bounce card theres beter out there

To all those who have made suggestions:Stony Silence - kataki's wage does more against more decks.Negate/dispel - swan song and spell pierce are better, straight up.Duress - play test the deck and you'll know that the hand disruption is already super potent.Celestial purge - subpar removal and there's plenty of premium already here.Check lands - originally were in the list but we're removed for resilience to moon blood ;)

Oh, and lingering souls! While I love it, I feel like the 3 drop slot is well covered.. Talk me into removing something for the spot?

Swan song kills your delvers. That seems really bad. Spell Pierce seems much more appropriate.

Or it just hits my face for two. The thing about the birds is it's still good long game.
