That could work well actually, for people that aren't interested or don't want to invest all the time it takes to do normal pvp or pet pvp, beastmoon is a great alternative since you can just go straight into it, and it would make for a great, more accessible alternative to gain arena tickets.
I don't really like this beast moon events that's going on lately right now since too many players are forcing to quit/flee then just don't participated but I would suggest maybe they should do PVE Beast Moon Deckathon vs Random Beast Moon Creatures in the building instead of players vs players just let dev knows there is so many rude chats I am always in this event every time I am in there
