Second, it shows me that some cards I believe to be underrated actually arent
Deck reports After you've built a deck, you can view reports detailing the statistics for the cards you've assembled
For example, you may find two: Iona, Shield of Emeria and Unburial Rites
Two-Mana Prowess Duds There is a long line cards that get people excited for in the two-mana slot in Prowess and ultimately disappoint: cards like Khenra Spellspear, Balmor Battlemage Captain, Electrostatic Infantry, Sprite Dragon
The Ruby part of this deck includes the very handy Sumerian Talisman (that allows the player to draw a card every time one of their characters is banished in a challenge) and 2 copies of Dragon Fire to banish any opponent character you may struggle to deal with
This is a bit extreme, but it works
