Season 1

Xmithie first entered the League of Legends in January 2011, quickly hitting level 30 and jumping into ranked duo queue, playing with his now ex-girlfriend. For a time during Season 1, Xmithie got stuck and hovered around the 1700 ELO range. However, once he began play solo in ranked, he sprang up to 2200 ELO, where he met other 2000 ELO players to form a team called Soldier Front. Team Soldier Front competed in small tournaments, eventually meeting APictureOfAGoose during a Go4LoL cup in October 2011. After playing against Team Soldier Front, A PictureOfAGoose invited Xmithie to join as their AD Carry substitute player, a position which he accepted.

Season 2

As being a part of one of the teams that qualified through the North American Pre-Qualifier #1 for the IEM Season VI - Global Challenge Kiev, Xmithie planned to go with APictureOfAGoose to the event. But, due to family problems, LemonGoD was unable to attend the event. As a replacement, team captain Atlanta invited his friend cuRtoKy to join as the support player for APictureOfAGoose. Atlanta decided to change to the AD Carry position in order to play with cuRtoKy, since they were close friends and Atlanta believed he would synergize better with cuRtoKy more than Xmithie would. Xmithie took Atlanta's old position of jungler for the team. Despite the roster changes, APictureOfAGoose ended up not attending IEM Kiev.

Around one month after the departure of LemonGoD and the addition of Xmithie into the main lineup, APictureOfAGoose was acquired by mTw and became mTw.NA. This occurred while APictureOfAGoose was competing in the Alienware Arena North America: Winter, where they ended up placing third.

In the next few months, Xmithie found success with mTw.NA in various minor tournaments, taking first place in Go4LoL Cup #61, CSN playLEGENDS Points Cup 1, CSN playLEGENDS Points Cup 2, CSN playLEGENDS Points Cup 4, and the In2LOL Kickoff NA Tournament.

The first major tournament that Xmithie competed in under the mTw.NA banner was the 2012 MLG Pro Circuit - Spring Championship. At the event, Xmithie faced off in their first match against European powerhouse Counter Logic Gaming EU, who proved to be a tough opponent as CLG EU pulled out a 2–0 victory over mTw.NA. Dropping down to the loser's bracket, Xmithie and his team were able to take out vVv Gaming 2–1 to advance to the next round of the loser's bracket. But here mTw.NA fell to Team Dynamic 2–0, ending the tournament with 9th-12th-place finish.

Despite a disappointing showing at the MLG Spring Championship, Xmithie and mTw.NA continued to dominate the online tournament scene, taking first at the Solomid NA Invitational 3. Here, Xmithie and his team fell to Team Dynamic 0–2 in their first match of the tournament, dropping down to the loser's bracket of the third SoloMid Invitational. However, here Xmithie and mTw went on a hot streak, sweeping Lzuruha Gaming, Ordinance Gaming, and Team SoloMid 2–0 to advance to the loser's bracket final. There, mTw.NA continued forward with their momentum in tow, taking out Counter Logic Gaming Black 2–1, qualifying straight to the grand finals as Curse Gaming forfeited their remaining matches. Coming back up from the loser's bracket to face off against the team that put them there, Xmithie and mTw.NA came out on top in a close 2–1 victory in the first set and swept Team Dynamic 2–0 in the second set to take home first place from the tournament.

Continuing their success in online tournaments, Xmithie took first place on July 6, 2012, at the National ESL Pro Series Season 3 with his team mTw.NA. During the three-month-long online group stage, mTw.NA placed third, going 4-3 winning 9 games out of 16 by defeating 4Nothing 2–0, Epik Gamer 2–0, Counter Logic Gaming Prime 2–0, and Team Legion 2–0, while falling to Team Dignitas 1–2, Curse Gaming 0–2, and Team SoloMid 0–2. As Team SoloMid was forced to forfeit, mTw moved on up to the grand finals. There, Xmithie carried on the momentum and defeated Team Dignitas 2–0, taking home first place with his team mTw.NA.

Two days later, Xmithie took second place at the fourth SoloMid NA Invitational with team mTw.NA. Xmithie had a powerful start in the first two rounds, eliminating both Curse Gaming and Team Legion 2–1 to advance to the winners bracket final. But there Xmithie's team mTw.NA were unable to pull out a win, falling just short to Orbit Gaming 1–2. Not letting the loss get to them, Xmithie and mTw.NA were able to sweep heavy favorite Team SoloMid 2–0 to get another shot at first place. However, once again Orbit Gaming was able to pull out on top, taking mTw out in a close 2–1.

Xmithie participated in the Leaguecraft ggClassic Presented by Arqade with his team mTw.NA. In the group stages, his team pulled out an impressive 4-1 finish, taking second place, defeating 4Nothing, Orbit Gaming, Taipei Assassins, and Counter Logic Gaming Prime while taking their only loss to Counter Logic Gaming Black. In the playoffs mTw.NA fell to Team Dynamic 1–2, dropping down to the loser's bracket. There, mTw.NA took out Curse Gaming 2–0 to move forward to the second round of the loser's bracket.
