Ruby cards focus on offensive strategies, like using the Rush (able to challenge the turn the character is played) and Evasive (only allowing other Evasive ability characters to attack the character) abilities
Unless I'm mistaken, Markov Baron is the only card with both madness and convoke, so when your mana is tapped out and you're faced with a Mind Rot or need to crack a blood token, three creatures can save this baron, it's sweet
You stay untapped, react if needed, then move into your draw step already holding the answer
