Force of Will
 
As an engineer, I sometimes like to joke that the universal plan B for engineering is to take a hammer and hit whatever the thing is until it fits. That's only partly a joke. It works with IKEA furniture, it can be adapted to computers by just plugging whatever cable you have into wherever it can go and stay, and it was famously used to complete Beijing's Olympic venue on time. I like to think of Force of Will as the universal plan B for planeswalkers. It works on just about anything, and the opportunity cost of reverting to it is usually worth it; but just as you should be wary of putting too much force into your hammering or, sometimes, of putting too much weight on it for a while, you should save some of your Fact or Fiction-style cards when you have to Force something. Blue decks, like engineers, are solution-oriented, and for all Force of Will's applications, it's still a reaction, not a solution per se.
