I purchased 50 Legendary, ~500 Rare, and ~50 Epic packs.
I also bought enough raffle tickets to evolve my hydra to the max level.
I am going to need to open more packs (likely just legendary packs) to get the last few legendaries so I have one of every card and earn the Demigod board. I believe this will be the most expensive tradable asset outside of diamond cards and mythic cards.
What I ended up with after spending 13.4 ETH on cards:
I do plan on doing some live streams playing with the new cards.
There are only a few more days to buy packs before they will no longer be available.
