History of CR 121.5

Every distinct wording since 2010, newest first.

July 12, 2019 · Core Set 2020
If an effect moves cards from a player’s library to that player’s hand without using the word “draw,” the player has not drawn those cards. This makes a difference for abilities that trigger on drawing cards and effects that replace card draws, as well as if the player’s library is empty.

If an effect says to “move” a counter, it means to remove that counter from the object it’s currently on and put it onto a second object. If either of these actions isn’t possible, it’s not possible to move a counter, and no counter is removed from or put onto anything. This may occur if the first and second objects are the same object; if the first object doesn’t have the appropriate kind of counter on it; if the second object can’t have counters put onto it; or if either object is no longer in the correct zone.

If an effect says to "move" a counter, it means to take that counter from the object it's currently on and put it onto a second object. If the first and second objects are the same object, nothing happens. If the first object has no counters, nothing happens; the second object doesn't get a counter put on it. If the second object (or any possible second objects) is no longer in the correct zone when the effect would move the counter, nothing happens; a counter isn't removed from the first object.
