The same goes to Harsh Mentor, this card in diverse metagame is not good. Against some decks you need 4, against many you'd rather see anything else than a 2/2 that occasionally hits an opponent for 2 (fetchland usually).
I think you're right that Harsh Mentor gets worse the more diverse the meta. OTOH, in a meta full of Ravagers and Ballistae, Harsh Mentor can really shine. Every time a player sacs an artifact to pump Ravager, every time a counter is removed from a Ballista to ping someone or something, every time a counter gets added to a Hangarback Walker, every time a Factory gets animated (or pumped), is a good opportunity for a Mentor to do 2 damage to that player. A single Harsh Mentor can severely disrupt a Ravager deck and multiples can be totally deadly.
On the gripping hand, Oath decks, Landstill decks, Two-Card Monte, PO decks, and just about everything else is not going to tremble in fear at a 2/2 that has little to no effect on them. If there were ever a time for maindeck Harsh Mentor to shine, the current prevalence of Ravagers should be it. (But it probably isn't.) Sideboard may be different. If this deck wants Mentors at all, think more about sideboard.
My 2 cents.
I wrote a guide to building and playing UR Delver if you guys wanna check it out: http://sylvanstudies.com/2017/11/01/vintage-ur-aggro/
Also have you guys tried Chart a Course? By no means is it a deck breaking card, but it’s honestly not bad, and it helps solve some issues we have late game. I feel like it’s worth trying in some builds, especially Aggro focused ones.
I have been playing Chart in my Legacy UR Delver build. It's pretty good. I haven't tested yet in Vintage (in fact I have barely played any vintage for the past couple of months). One guy I know says it's very good and has 4 in his build.
A four of seems like a lot, but since cards like Brainstorm and Probe are restricted (and mental misstep is in the format too), it makes sense. Although I feel like three to two is a good starting number.
Come to think of it, Chart a Course might actually better in Vintage than in Legacy because of Mistep and the restricted list.
I'll test chart a course as well, it seems a nice potential addition.
A question for you guys : I already have an ancestral & a time walk, I'm thinking about which piece of power to buy next - keeping in mind I almost exclusively play UR aggro.
Would you go for a Ruby ? A library of alexandria (not power, but nearly the same to me) ? Or wait 2 or 3 month until you can afford a sapphire ?
Yaaaayyyy thread necro.
I'm interested in Delver, but the archetype's been pretty quiet in 2018. There are a few lists on mtgtop8 from earlier this year, but for the most part, it seems like it's been supplanted by Pyromancer and UWR lists.
Is Delver just worse than the other Xerox decks? What would a 2018 Delver list look like?

@stuart I played RUG delver to 6-0 in vintage side events at EW and then a top 4 in an event the week after. It’s not dead at all. The problem is no one wants to break outside of comfort zone. Why play a 1/1 when you can draw half your deck with PO turn one lol. I enjoy delver a lot in vintage and I think it’s a good choice for sure.
@stuart sorry I suck at responding. Yes- that was me! If you’re friends with the guy I beat round one on PO and got salty about losing to the green machine!! But my list was:
2 young pyro
1 time walk
I really like Delver. I like that it is aggressive, plays blue cards, Pyroblast, Null Rod and Wasteland.
I considered playing it at Champs but decided to go with Survival instead because I was wary of playing a fair deck in a large tournament (and Survival is the new hotness, etc) but I had a decent amount of success (in the small sample size that I was able to play) with both URg and URw online. I was especially liking URg:
I went 33-7 with a few different versions of URg Delver in August and September of this past year. Some leagues, a lot of tournament practice matches. I especially beat up on DPS and Outcome but I didn't play Shops much and didn't trust that matchup because of that.
