This means indirect damage (cards that say player loses x life) count towards this objective
The Ruby/Emerald deck made it this high because of how effective it can be in formats limited to Starter Decks
Ruby has the highest density of cards that interact directly with opposing characters, making it a great choice for controlling the flow games and a perfect complement to amethyst
Each character also has a Strength value that tells the player how much damage they can cause, and a Willpower value that tells the player how much their defense is, or how many attack points it will take to banish that card from play
The commander gets bigger whenever you play a non-creature spell, so if you chain some small spells together you quickly reach a point where he can be activated to pay for a big one
While the main focus of this set was obviously cramming in as many important characters as possible, it's not only new cards - there are some choice reprints as well
