Forum:Determinng what cards can Miss the Timing

I worked on a page called. When I did, I was trying to explain how some Loops can be allowed and others are not. i was wondering if a page can be made that explains the difference between (When.../then...), (When.../you can...), (If.../then...) and (If.../you can...). Is this a good idea? References would also have to be made to make sure people understand it better.
