I was targeting a "Fire Nation Cadets" with "Sold Out". In response my opponent cast "Octopus Form" on his "Fire Nation Cadets". I had "The Fire Nation Drill", so I let "Octopus Form" resolves in the stack before I was gonna activate "The Fire Nation Drill" ability, but the game never gave me a chance to do it... It should have let me get the priority between "Octopus Form" getting resolved and "Sold Out" getting resolved.
