***vs mono G Stompy:

-3 Counterspell

-1 Daze

-2 Faerie Miscreant

+1 Augur of Bolas

+2 Skred

+2 Electrickery

+1 Swirling Sandstorm

Notes: Preboard, I consider this matchup to be slightly unfavorable, but postboard, I consider this matchup to be slightly favorable. Counters are bad in general against Stompy because they're too mana inefficient (except for dispel which can stop a key Vines of Vastwood or Hunger of the Howlpack), and UR Delver can just burn everything instead. I rarely try to race, and instead frequently use Delvers and ninjas on defense to trade against 2/2s. Eventually, UR Delver will out card advantage Stompy.



***vs mono U Delver:

-4 Delver of Secrets

-1 Augur of Bolas

-1 Daze

-1 Lightning Bolt

-1 Vapor Snag

+2 Pyroblast

+2 Skred

+2 Stormbound Geist

+2 Electrickery

Notes: I consider this matchup, both preboard and postboard, to be extremely favorable. Delvers are unreliable on defense, and can't get through Stormbound Geists and Spire Golems on offense, so I side them out. UR Delver can easily land a ninja, and ride it to victory by killing everything in its way. Otherwise, UR Delver can try to set up a board stall. Eventually, either mono U Delver will have to attack and make bad trades, or UR Delver will draw enough burn to clean up the board and win.



***vs UB Flicker:

-3 Lightning Bolt

-2 Skred

-1 Vapor Snag

+2 Stormbound Geist

+2 Pyroblast

+1 Augur of Bolas

+1 Counterspell

Notes: I consider this matchup slightly favorable preboard, and favorable postboard. Removal spells are not that great because they're negative card advantage against UB Flicker, and I find this matchup to be all about card advantage. UR Delver has slightly more value creatures than UB Flicker, and they're also cheaper. Also, Gush from UR Delver is easy to resolve, whereas Mulldrifter is not. In addition, in the late game, fetch lands plus the low land count from UR Delver means that UR Delver will just have drawn a few more spells than UB Flicker.



***vs Murasa Tron:

-4 Lightning Bolt

-2 Skred

-1 Vapor Snag

+2 Pyroblast

+2 Hydroblast

+2 Stormbound Geist

+1 Counterspell

Notes: I consider this matchup to be slightly favorable, both preboard and postboard. Because of their inconsistent manabase, UR Delver gets a lot of free wins. If they have mana, but don't have tron, their cards are too inefficient to keep up with UR Delver. If they have tron, UR Delver still has a reasonable shot because UR Delver can keep up in card advantage, and their big spells can still be countered cheaply.



***vs Kuldotha Tokens:

-4 Delver of Secrets

-2 Skred

-1 Daze

-1 Vapor Snag

+2 Stormbound Geist

+2 Electrickery

+2 Gorilla Shaman

+1 Augur of Bolas

+1 Counterspell

Notes: I consider this matchup to be even preboard, but favorable postboard. This matchup is mostly about value since both sides have enough removal spells to stop any fast starts from each other. Delver doesn't generate value, so I side them out. In general, UR Delver has slightly more value creatures, as well as more counterspells to stop value creatures. Postboard, UR Delver gets Electrickery to stop one of the main ways Kuldotha can win against UR Delver, and Gorilla Shaman as another value creature. (I usually target clue tokens before lands with my Gorilla Shamans.)

***vs Bogles:

-2 Skred

-1 Dispel

-1 Augur of Bolas

+2 Electrickery

+1 Counterspell

+1 Swirling Sandstorm

Notes: I think this matchup is slightly unfavorable preboard, but slightly favorable postboard. In the dark, I keep in Lightning Bolts to kill Scattershot Archers. If I see Aura Gnarlids, I'll swap the Bolts for Skreds. I'll usually let any aura that doesn't pump toughness resolve, and I'll let myself get hit down to very low life totals to keep up open mana. I think I would max out on Electrickerys and then start adding Curfews if I had to fight Bogles more often.



*First of all, great guide and write up, definitely a huge help. Any idea how to board or play against Affinity in general? 5 out of 8 matches have been against Affinity today and I am not sure what to do against them.

[–]kungfutrees[S] 2 pontos 10 meses ago
There are several different builds of Affinity, so sideboarding is a little bit more fluid. In general, I'll cut Dazes and Dispel, and trim on Delvers, Augurs, and Counterspells. I'll also trim on Bolts if they don't have Somber Hoverguard, Auriok Sunchaser, or Disciple of the Vault. I'll add Gorilla Shamans, Hydroblasts, Skreds, at least one Pyroblast (more if you see Gearseeker Serpent), and probably Swirling Sandstorm. (I'm still testing out Swirling Sandstorm :).)

I think the matchup is unfavorable preboard, but favorable postboard. Gorilla Shaman is easily the most important card in the matchup. If I do draw Gorilla Shaman, I try to wait until I can get 3+ lands with it, and I also aggressively go after Springleaf Drums, Flayer Husks, and even Chromatic Stars. (Affinity is usually the only matchup in which I will actually play Ash Barrens instead of cycling it to allow Gorilla Shaman to eat an extra land.) If I don't draw Gorilla Shaman, I usually try to race with Delvers and ninjas. (For example, I'll usually Skred the 4/4 on defense instead of trying to preserve my life total.)


***vs Izzet Blitz

+2 skred +2 pyroblast +2 hydroblast +1 swirling sandal (maybe)

-4 delver -1 daze - 1 counterspell - 1 augur(maybe)




***vs boggles

+2 electrickery +1 counterspell +1 swirling sandal

-2 skred -1 dispel -1 delver


*** Vs Mirror Match
Yeah, I definitely treat it as a value game. With the decklist linked in this post, I would go:

+2 Electrickery, +3 Pyroblast, +1 Augur, +2 Stormbound Geist

-4 Delver, -1 Daze, -1 Vapor Snag, -2 Skred


***Vs Elves
I think Elves should be a pretty good matchup, especially postboard. I wouldn't side out ninjas though, since they reset Spellstutters, are good blockers, and are also annoying to block for Elves, My sideboard plan is:

+2 Electrickery, +1 Swirling Sandstorm, +1 Counterspell

-1 Daze, -1 Dispel, -2 Delvers


***Vs Midnight Gond
I've only played that matchup once (and won :P), so I don't have a whole lot of experience, but for your list, I would probably go:

+2 Electrickery, +1 Relic of Progenitus, +1 Swirling Sandstorm

-2 Skred, -1 Dispel, -1 Augur of Bolas

My impression of this matchup is that Gond is really slow to get started and also somewhat inconsistent, so UR Delver can easily win with a good start. Otherwise, if the game goes long (and UR Delver is forced to play defense), I would look to save counters mainly for Spidersilk Armor and start digging for board sweepers. Once you have board sweepers, I would wait a little bit longer for another few counters for Prismatic Strands. If the sweepers resolve, the game should be pretty easy to win from there.

-----UR Delver is clunkier than mono U Delver, and gets nut draws far less often, but it is much better at catching up on the board, so being slower doesn't hurt UR Delver as much. Also, the addition of red sideboard cards makes the matchups against Elves, tokens, and Affinity quite a bit better. The red removal spells also kill Scattershot Archers, and just make the matchup against green decks much better.

UR Delver also loses Spire Golem, but I think Augur is better than Spire Golem in every matchup except vs mono U Delver anyways.
