The delver decks are similar. The non-rug lists are less focused on your mana so they should be easier. Against Patriot, things like needle and o-stone are relevant because of slower equipment and sfm. UR delver i side in counters to be able to counter price of progress and force things through(like a crop for chasm). Repeal is king against all of them, severe tempo advantage AND card advantage for low mana really messes up their strategy.
While shardless has some nutty draws that will leave them up 7 cards on you, it's again a little less focused than the Jund. Overall they have a lot of weak cards against post, so avoiding devastating hymns and slowing down their draws by controlling DRS is strong. Top is important if games get into the jace zone. Overall I think it's a very positive matchup.
