Mono Blue Delver is the most powerful budget deck in Modern that nobody is playing!

[Captain Hammer]

Monoblue Delver finally has all the tools it needs to be a competitive deck in Modern now, and it’s the single best budget deck in the format imo.

Here is a sample list..

17 Island

4 Delver of Secrets
4 Pteramander
3 Cryptic Serpent

4 Thought Scour
4 Opt
4 Serum Visions

3 Spell Pierce
3 Spell Snare
3 Remand
2 Mana Leak
1 Disrupting Shoal

3 Dismember
3 Vapor Snag
1 Repeal
1 Psionic Blast

The list above is different from UR aggro lists in a number of key ways. It plays a much lower curve. This allows it to function off of just 17 lands and draw business more consistently, but also means the curve is too low to support numerous Snapcasters, Nimble Obstructionists or Vendilion Cliques. Although including any of these cards in your variant wouldn't be wrong, as long as you keep the total number of 3cc spells to under 4.

It plays a record number of conditional counterspells. This is why you absolutely never want to tap out on your turn until the midgame (to play a threat that will close out the game in a couple of turns). This is why it plays zero sorceries and zero Thing in the Ice. You want to only play your cantrips at the end of your opponents turn once you're certain that they haven't played anything that you want to counter or bounce or dismember. Thought Scour is an amazing card here. It routinely functions as a Dark Ritual with a cantrip attached to it. The rest of the list is self explanatory.

Any questions or feedback is welcome.
