What league will you be playing in?
Most of the comparisons have been done for Champ decks and mostly talk about leaderboard positions.
As well as the metrics you're suggesting it would be interesting to see a comparison between soulbound and gladius cards usage too.
Champion! I usually end the season in Champ 2 and spend the first 3-5 days in diamond.
I'll keep an eye in the soulbound cards, although I'm less interested there as the cards I have are RNG instead of hand-picked by me (e.g., I only have level 1 Iziar still).
Gladius cards I'm also not too interested in - I think the 6 mana summoners are overcosted, and the gladius ruleset means the opponent can use it too.
A big part of why I want to follow Rebellion is that part of what I'm interested in seeing is how quickly the bots adapt. The set has been out for 3 or 4 weeks now, plenty of time for the bots to get a handle. So I want to see how good they are at using Rebellion, as a proxy for how good/fast they are at evolving and learning the new meta.
