Use the "there is a" operator:

To check if a card exists:
   if there is a card "My Card" then... -- in the current stack
   if there is a card "My Card" of stack "My Stack" then...

To check if a stack is loaded into memory:
   if there is a stack "My Stack" then...

To check if a stack exists in a particular file (loaded into memory or not):
   if there is a stack "My Stack" of stack "/Disk/Folder/File.rev" then...

To check if a stack is a substack of another stack that's in memory:
   if there is a stack "My Substack" of stack "My Main Stack" then...
