Karaslavov began his career with Asenovets, before he was scouted by Botev Plovdiv in 1994. He joined the first team of Botev after the 1999–00 winter break, in January 2000. Karaslavov made his professional debut on 5 April 2000 in the Bulgarian Cup match against Neftochimic Burgas, coming on as a substitute for Kostadin Vidolov. He made his A PFG debut on 20 May, in a 1–0 home loss against Chernomorets Burgas. Karaslavov would play five more matches that season.
The 2000–01 season saw Karaslavov breaking into the starting lineup on a regular basis under managers Marin Bakalov, Dimitar Mladenov and Dinko Dermendzhiev. He scored his first A PFG goal for Botev on 5 August 2000 in a 3–1 home victory over Hebar Pazardzhik. During the season, he earned 22 appearances, scored two goals.
In 2001 Karaslavov signed a three-season deal with Slavia Sofia. He made his team debut on 3 August 2001 in a 0–1 away victory over Cherno More Varna. He took over the captaincy of Slavia when Dimitar Rangelov was transferred in 2006, a responsibility he held until leaving the club in 2007.
On 19 June 2012, Karaslavov re-signed for Botev Plovdiv on a 2+1 year contract. On the eve of the 2012–13 season, he was selected for captain of the team. Karaslavov made his second Botev debut in a 3–0 win against Slavia Sofia on 11 August. He retired at the end of the season because of having too many injuries and became director of football.
