Last ditch effort is you Get titan out, and pull a glacial chasm to stabilize and build back up with glimmerposts. Hydroblast kills off Pyromancer. Essentially knowing what delver variant you're against is super crucial information.
Without dissecting your decklist, your real decent answers are Engineered Explosives, Pithing Needle, Trickbind, Repeal, Bojuka Bog (depending on the version), Hydroblast (depending on the version) Cavern of Souls. If you are able to get any of your creatures out you should be able to win, typically their answer is Liliana if a creature gets on the board. I wouldnt side out Repeal ever, it's an answer for their creatures on the board and even a liliana if it's annoying you enough or will lock you out of a creature on the field. In B/U builds, I don't like Moment's Peace at all, feels too clunky and I rather run a counter or some other toolbox item.
-3 Maps, -2 Moment's Peace, +3 Engineers Explosives and +3 Flusterstorms. That would be my simple Sideboard with your current list.
Now, I have some suggestions and comments on your list. This build feels incomplete. It feels like you are trying to build up from a mono green version to the G/U version. I would suggest stay at the Mono green until you get a complete list that way you have much better matchups.
First off, 2 Cavern of Souls but you are only running Titan and Eldrazi. Why not just run another Vesuva for better toolbox ability?
No Karakas? Why not? This variant needs a way to recur Emrakul to win! Eternal Masters reprint made that sucker only 30 bucks! Sell or Trade that second Cavern and get a Karakas!
I've tried Moment's Peace and haven't liked it. If you run Glacial Chasm, that is your fog effect backed up by Glimmerpost.
Your only permanent removal is Ulamog, Emrakul, and Repeal. 4 cards in the entire deck to delay the opponent. This isn't enough in my opinion. You either run counter magic, being in blue, or mass removal to deal with the battlefield states.
You have no board wipe like answers. Run Ugin, Oblivion Stone, Terminus, or All is Dust. This helps against things like Delver, Eldrazi Stompy, or Death and Taxes who get a lot on the board.
Another decent removal+creature, World Breaker. Has a cast trigger which can't be stopped by delver typically and is great spot removal outside of running Swords to Plowshares.
I keep promoting my build because it seems to be working really well for my meta which is heavy Miracles, DnT, and Delver variants at the moment. Try running the Bant version and see how it plays out for you.
