While the comic cover chosen for Hawkeye (Ronin) does depict the Ronin costume, it actually depicts someone other than Clint Barton wearing the costume. Instead it depicts Maya Lopez, the first Ronin.
Here are some alternatives that do depict Clint Barton as Ronin:
New Avengers #27
Dark Reign: The List - Avengers #1 (second printing)
There are a few other covers out there, but focus on multiple characters.
1v1 Blackcat is really dynamic and will be a fantastic COTT match.
Ronin is a great third partner that wipe out enemys. My only real complaint about Sabertooth is that I wished match 3 were processed BEFORE the 3x3 explosion, but otherwise I found him to be easy to use and consistent in his output.
i’ll be Keeping an eye open for opportunities to earn these covers.
The new new designer deserves an attaboy, for new mechanics and chars that integrate well with the existing meta. They will never replace an existing 5* combo in a mandatory featured event, but they are absolutely a great option in 3x3 matchup
