Mihaylo ‘Kas’ Hayda’s RTS career began with WarCraft III. He only started playing it at a late stage (2007-2010) but soon became a strong player before the release of Starcraft II and winning 3 ZOTAC cups. Being a Human player in WarCraft, he picked Terran for Starcraft II. After numerous cup victories, he was the first player aside from the seeded ones to qualify for TSL3 through winning TL Open #8.
Kas has enjoyed much success in many of the weekly tournaments that he plays on the Europe server. He earned multiple wins in the Go4SC2 ESL events and ZOTAC Cup events. He is currently 5th in the ZOTAC Cup hall of fame with three first place finishes. Kas has a very solid and conservative style which aids him very well in these weekly tournaments which are frequently Best of One series until the last 16 players. Kas also took out the HomerJ XMAS Cup 2010 and the GosuGamers Holiday Special with clean 3-0 victories over MaNa and SjoW.
