Shields Up

Description
Gain 40.

Strategy and Synergy
Shields Up can be used in nearly any deck. The effect of gaining 40 for 1  is always good. The problem is, it doesn't do much outside that without upgrades. In total, it's a well-balanced spell that fits into every deck as a defensive option.

is a good choice for this spell - it gives 80 for 2, and because Shields Up doesn't deal damage or fire projectiles, it has a very small pool of possible upgrades, making Double easy to find on your first attempt.

Trivia
The flavour text is a reference and subversion of the common adage, "The best defense is a good offense."
