Add a log of cards received

You know how oftentimes, opening packs will be bugged, and players will have no visual confirmation of getting cards?  One solution would be to add a log of cards received.

Then, when one gets "Something went wrong" and then sees the pack gone, one could check the log, and if one sees "17 Jul 2017 20:40 GMT; Amonkhet pack; Open Into Wonder, Aven Wind Guide; Minotaur Sureshot; Scribe of the Mindful; Shimmerscale Drake", then one would know the cards were actually received.
