I’m a very active League player and have access to LoR. If the Testing period is anything to base off of, I was able to build a couple decks off of just the first few A.I. I’ve fought, and I haven’t completed the tutorial line of Rewards yet. XP and cards are very easy to grind out in the beginning. Games don’t take too long, and the A.I. decks change regularly to keep it interesting. I’ve dabbled only a few times in Hearthstone, so I don’t know how it compares, but as a huge League fan it’s definitely nice to have something new coming from Riot. A key note, however, is that I assume that because it’s a Testing period, you are granted quite a lot of Wildcards to start. I’m not very confident this will carry over into the Live game, but it doesn’t actively detract from how quickly Cards and Wildcards are earned.
