Is it possible to complete gwent deck after main story

[DeadByLag]

I realised I might have missed some cards during a main quest run

http://guides.gamepressure.com/thewitcher3/guide.asp?ID=30999

With the main story concluded, are there alternative avenues to obtain missing cards? I had long beaten the tournament quest.

Side note: I noticed my "A Miraculous Guide to Gwent" book now reports only two opponents left in Velen. I am pretty sure I haven't played against everybody in Skellige yet. And further more I saw that my gwent challenge option against the innkeeper at Kingfisher (Novigrad) was not exhausted. What exactly does the book report with its numbers?

if you missed quest specific cards and there're several you're screwed i think... unless you use debug console

Did you get those 3 cards from zoltan instead of the money?

Thats another instance you wont be able to go back to.

i lost high stakes quest and got screwed

Did you get those 3 cards from the ball with Triss?

That's yet another instance you won't be able to come back to.

Yes, I got cards from Zoltan's [A Dangerous Game].

Yes, I won all matches at the banquet during [A Matter of Life and Death].

I've played against every suggested character and innkeepers via quests' demands, including Dijkstra, Roche, Thaler, Lambert.

My deck is not complete; I know I am still missing several leader cards (since those show up in the interface) but unsure what other unit cards I have yet to obtain. I had long exhausted the number of cards I could win from "nameless" characters even before I was half way through the Skellige isles. The book's reported numbers confuses me as well since I did not actively pursue every single possible person in Skellige.

I have all the leader cards except for their respective fifth cards.

Those "fifth" leaders cards will be available on Hearts of Stone (first expanssion), aside with other cards too (cow, toad).
The achievement should've popped out when you complete the deck on the base game, there are others but no related to Hearts of Stone, instead the second expanssion, Blood and Wine (Skellige deck).

A person in distress in velen sells gwent cards after you rescue him.

EDIT: Sells one of those dragon hunters and something else, you missing that?

Matching up the list looks like I am missing

NR

• 1 Poor Farking Infantry

Nilfgaard

• 1 Etolian Auxiliary Archers
  
• 1 Black Infantry Archer
  
• Heavy Zerrikanian Fire Scorpion
  
• RainFarn

Scoia'tael

• Vrihedd Cadet - but I have an unlisted Vrihedd Brigade Recruit?
  
• 1 Dol Blathanna Archer (strength 6?) - It only lists 2 Dol Blathanna Scout while I have 3. I suspect this is a mistype since the scout is strength 6 while archer is strength 4, so the numbers ultimately taly.

Neutral

• Avallach'h - I take it this is the "Mysterious elf" card I have

Wow the guide is really misleading. The merchant selling all these cards is not at Midcopse but at Lidenvale. I don't know if there was some version revision to the game or what, but that sent me on a wild goose chase for a while.

Side note: turns out there're 4 Poor Farking Infantry cards.

But finally the deck and quest is complete. Thanks.
