For the sake of argument, please pretend that you are satisfied with the rest of your Spellbook and that you are certain that what your Spellbook needs most is either a [mwcard=MW1E05]Cheetah Speed[/mwcard] or a [mwcard=MW1E28]Mongoose Agility[/mwcard]. Also, for the sake of argument, please pretend that you only have enough spell points for one of the two, not both.
Yes, we all know that it depends on the Mage and the Spellbook, but for the sake of argument let's pretend it doesn't. Generally speaking, which of these two cards is better? If you had to choose between these two cards, which of the two would you pick and why?
