I think it's really smartly designed. It takes a lot of the good aspects from other card games and combines them into a nice f2p friendly bundle. One thing that really struck me was the draft mode. Normally in card games draft decks are all very similar. Everyone's just trying to curve out. Everyone's playing the same thing, and that thing isn't very complicated, which makes matches kind of 1 dimensional. I know a lot of people like it, but it's just never appealed to me. But in LoR, the drafts act like Dungeon Run, where you're offered different synergistic buckets. I've drafted 2 decks and both times I got something interesting and unique to what my opponent was playing.
As someone who refuses to spend money on these games and doesn't like typical draft modes, having this version, where I can play something that suits my tastes until I get a collection built up, is really nice.
