[12] Yasooka is currently the lead designer for the Hobby Japan developed trading card games Final Fantasy[13] and WIXOSS.

[15] This finish qualified him for Pro Tour Honolulu, and served as a catalyst for a spectacular run the following season.

[16] To follow up on this finish, Yasooka made the top eight individually at the next premier event held in Asia, Grand Prix Kuala Lumpur.

He added three more Grand Prix top eights to his resume, in Sydney, Toulouse, and New Jersey, before the end of the season.

Going into the World Championship, Yasooka had the lead in the Player of the Year race, and despite earning only the minimum two Pro Points there, no one was able to pass him.

[18] At the end of the 2012 season, Yasooka had amassed 53 Pro Points, which was enough to secure himself a place in the first ever Magic Players Championship.

[1] Yasooka is also known for his fast and technical play style, an aspect of his game that is considered particularly impressive given his preference for control decks requiring much decision-making.

In January 2012, Paulo Vitor Damo da Rosa named Yasooka as the main player he would most like to add to Team ChannelFireball.
