LR-99: Battle Engine v1

Okay so setting these inits to `Command.__init__(self, name, explanation, time)` breaks the code. Here is the trace:
>File "C:\Users\cwang\Documents\GitHub\lord-of-the-rings\commands\enter_command.py", line 20, in __init__
    Command.__init__(self, name, explanation, time)
NameError: global name 'time' is not defined

I do not understand why this would happen when the parent class has a keyword argument for time.
