Blacksmith's card is actually really good for summoner class or classes that rely on minions. The huge boost of 75 armor for 3 turns really helps keep your minions alive and build up your damage during its effect. Know that armor can work with barrier at the same time, so spending 1 energy to play a "Barrier" spell that gives 10 barrier actually can midigate most damage due to armor beforehand, this saves energy for spending it on building damage for your minions.

Yea, most are very niche, except Master-at-Arms card which I use almost every time.

Is it just me or are these cards a little on the 'meh' side? I think the Master of Arms card is the only one that seems pretty worthwhile. The others seem a little debatable whether their utility is worth bloating your deck.

ok. got it.

The quest cards behave differently, though. And you pick one out of three, which come from a larger pool. So, you can't guarantee to get the one you want.

But I guess my sentence can be interpreted that you can't buy any cards from him lol.

I'll update the guide to mention that you can buy them from the Lost Soul to make it more clear. Thanks for pointing it out.

If you mean the Quest Cards, actually they can be bought on the Lost Soul Shop...
