In round nine yesterday, Robert Jurkovic was disqualified for stalling. Being 1-0 ahead, Jurkovic had no winning option left in his deck in the second game, but he did have an Emblem from Tamiyo, the Moon Sage. He used the ability to repeatedly cast spells without any influence on the game, even going so far as to countering his own spells.

He performed all his actions in a timely manner, apparently working under the assumption that physical lack of speed was the only mark of stalling. Head judge Frank Wareman clarified, however, “Players are expected to advance the game state. Playing just to advance the clock is most definitely not okay.”

from the mothership.

My question is somewhat related to this incident, imagine Robert was playing in a timely manner, but not wasting time (lets say he countered everything with dissipate every turn), although he did not have any way to win.

But he could not lose by keep playing, but also he could not win.

Would that be considered stalling too?

The list policy about not discussing active investigations still applies on the boards - closing this topic for now, unless one of the higher level judges wants to put in a reply.
