true...and of course the sorceror is not prevented from summoning invisible stalkers or skeleton warriors via project image, creating a large army of summons to flood the chavalier...
my point is that time delay tactics are to the sorceror's benefit..a bit of planning, and the sorceror can survive a lightning quick immediate attack, even kill the chavalier quickly...but if the chavalier decides to play a delay tactic, that works out even better for the sorceror...project image, and create some nice, long lasting summons, and start searching the battlefield...
