Who in your opinion are the most impactful artists on X-Men books since 2010? To give you some idea, 2010 is the era of Second Coming
I bet you Greg Land and Chris Bachalo have drawn the most X-Books since 2010. Bachalo, going back to his Generation X days, has to be considered a definitive X-Artist at this point. He's been with the line through many iterations and his work during the Bendis era has proved especially long lasting design wise.
So Bachalo is on the list I think.
Jerome Opena is a personal favorite of mine. I'm not sure his work on Uncanny X-Force was substantial enough to merit placement on the list but I adored his work. Mark Brooks is another artist from that run that I love and whose initial image of HOXPOX was iconic.
Does Copiel make the list? House of M, AvX, Brian Wood's first four X-Men issues....I'm not sure it does.
I think Stuart Immonen would have to make the list based on his talent and the way his art is the new house style for the X-books I would argue. Everyone from Larraz to Silva to Asrar are following in Immonen's footsteps (this is not meant as an insult - Larraz in particular is quickly on his way to surpassing even Immonen).
I really cannot think of who has impacted the line more than Bachalo or Immonen in this decade? Which is funny because while both are amazing artists, they are not the type I most associate with X-Men which were so defined by the semi perfect draftsmenship of Byrne, Smith and Lee.
Who am I forgetting? Who has made a lasting impression on you and on the line?
