One of my biggest struggles from Hearthstone was wanting a card but not having enough resources to manually craft it. This often lead to look for cards that I didn't normally play and destroying them in order to get a small brief of dust to craft the card that I wanted and this, meant that I had a particularly narrow collection, often focused on one particular class/playstyle.

However, I love NOT having to do this in LoR. I usually have a couple of wildcards sitting around my collection, so whenever I want a card, I can just go and craft it. As simple as that.

I also love the "no pack" thingy. I want a specific card, I give you my money and I get the card.

This two things combined means that I have a pretty sizable collection intact, so if I feel bored of my current class/playstyle, I have a good amount of cards to go ahead and form a new deck.

Yeah, I may be lacking a couple of cards, but here's where the wildcards become so damn handy.

TL;DR: Thank Rito for the Wildcards. It allows me to keep my collection untouched and safe.
