@all - Don't remember who was asking about Gwent Collector Achievement but - little tip that i think wasn't explained in game - In order to obtain achievement you only need to collect cards that have unique name. So for ex. you only need 1xGhoul (even though there are couple of them in game), 1xDecoy, and so on. Leader Cards are exception to that rule - you need to have all 4 of them in each faction. I hope it helps
Cards from White Orchard's Inkeep should be attainable from other merchant in White Orchard in today's patch for PC (it was too late for console patch but it will also be patched for consoles soon). If i am not mistaken - there are some "failsafes"/alternative ways to obtain cards in some quests but probably not in all of them. This achievement seems quite hard and therefore prestige one
Challenge accepted?
@Blandock - Which Leader Card are you trying to use?
Foltest - King of Temeria (this one summons Fog card from your deck - so if you removed this weather card from your deck before match, or you have this fog card on hand then you can't summon it from deck)
Foltest - Lord Commander of the North (It clears weather effects that are currently on board - you cannot use it if there are no effects on board)
Foltest - the Siegemaster (Applies Horn effect to siege row - if there is no horn effect already present)
Foltest - the Steel-Forged (Destroys enemy's siege units but only if their combined strength is equal or higher than 10)
Or maybe other leader?
@lord_blex - If card has golden edge thingy (Hero mark), like the one below, it is not affected by any special cards (weather, scorch, ressurect, +1 in row, decoy - won't affect it):
So - for ex:
If enemy has 10 point [ Hero ] card on his side, and you have 6 point [ Common ] unit card on your side (and there are no other cards on board) then scorch will destroy your 6 point common card as it is highest non hero card on board.
