Ivan "Artstyle" Antonov is a Ukrainian player who is currently teamless.
Ivan was born in Kharkov, Ukraine on 21 April 1989. He has always been fond of computer games, namely Counter-Strike. Dota was the start of Ivan's e-sports career. Ivan has played for teams such as DTS, Natus Vincere, and Darer.
 Dota 2
Artstyle made his first steps into the Dota 2 competitive scene with Natus Vincere among the likes of Dendi and Puppey, as they competed in The International 2011. They went undefeated in the whole tournament, winning the unprecedented $1,000,000 winner's prize. Artstyle left the team in the following weeks, and eventually joined Darer. Artstyle and his teammates notably attended The International 2012, where they delivered a feeble performance as they placed last ex-aequo in the group stage. A few days later, on September 12, 2012, Darer decided to change its entire roster (because of internal, logistic and languages issues), hence leaving Artstyle teamless.
On September 19, it was announced that Artstyle had created the all Ukranian squad Team Kharkiv to compete in Star Ladder Star Series Season 3 and ESWC Ukraine. After a brief period playing unsponsored, Artstyle joined Eclypsia along with his teammates on October 4. He became the only player remaining in Eclypsia's roster after the departure of his four teammates on November 11, and was reported to be considering retirement.
