Amer Miracle- Al-Barkawi is a professional player from Jordan who is the first player in the world to reach the 9,000 ranking mark. He started his professional career in January 2015, playing for Balkan Bears. In July of the same year, he became the second player after w33 to reach the 8,000 rating mark. His success caught the attention of N0tail and Fly, who contacted him after The International 2015 and invited him to the new monkey business team. The team played very brightly and took first place in the European qualifications of The Frankfurt Major. They then rebranded as OG and won the first Major tournament of the season in November 2015.

Miracle- showed a unique play on Invoker, Shadow Fiend, and Alchemist, which attracted a large number of fans. The OG team in the spring of 2016 took first place at Manila Major and many believed that they would definitely win at The International 2016. However, OG lost to two teams from Southeast Asia and finished in 9th-12th place. After failing at the main tournament of the year, three players left the team, including Miracle-.

He was invited to join Team Liquid to replace the departed FATA-. With the new roster, they won at EPICENTER 2016 and StarLadder i-League Starseries Season 3 and received an invitation to The International 2017, where they placed second. In the following years, Team Liquid started taking silver more often than gold at big tournaments. They also took second place at TI9, which was the most difficult second place finish for the team.

In the fall of 2019, Team Liquid players left the organization altogether and created their own team, Nigma, where Amer started playing in the Carry position. It immediately started winning various tournaments such as OGA Dota PIT Season 2: EU/CIS, WePlay! Bukovel Minor 2020 and WePlay! Dota 2 Tug of War: Mad Moon. But over the next few years, the team experienced a decline in results. At the end of 2022, Miracle- goes inactive due to health problems. On December 22, 2023, Nigma Galaxy announces that Amer is returning to the professional Dota 2 scene and will continue to play for the Arabian club.

2024 started with qualifiers for many major tournaments, but Nigma Galaxy only qualified for Elite League 2024, where they finished twentieth in the tournament itself. Later, the team received a direct invitation to FISSURE Universe Ep.2 and Clavision Snow Ruyi Invitational, where Ghost replaced Miracle. The team also played at 1win Series Summer. In addition, the guys failed the qualifiers for two major events this year - Riyadh Masters 2024 and The International 2024.

In October, the team finished 14th at PGL Wallachia Season 2, failing to advance from the group stage. At DreamLeague Season 24, the roster suffered the same fate. Later, Nigma competed at the 1win Series Dota 2 Fall, where they finished in 6th place and placed 6th at ESL One Bangkok 2024.

BLAST Slam II Miracle- missed. He was replaced by Ghost, and the team reached top-3.
