nice report thanks for that one!

conserning your list:
could you see yourself cutting 1 ET, 1 CB, 1 TOP, 1 Expedition Map (is it needed?)
for:
1 STP (you really need that!!)
3 Spell Pierce (or 2 Spell Pierce 1 Spell Snare) or maybe even add 2 Ponder or even Terminus depending on your local meta of course.

you play 18 Blue spells including 4 force, I know this is the minimum requirement but I would feel more comfortable with view more blue spells.

especially for the RUG/UR-Delver matchups you need 4 STP. These are imo the harder matchups and I don't see many good cards against these kind of aggro decks beside CB and your combo which is often too slow or not?
