A nifty resource card that acts like a double resource, but more efficiently pays for 1-cost cards like Side Step, Never Back Down, and Preemptive Strike. I wouldn't call it a staple since you do need to have a critical mass of Defenses - otherwise the traditional double resource cards are better - but in the Flow Like Water archetype, this is a fantastic card.

An auto-include card in many Protection decks and a combo card that synergizes well with Magik in Protection aspect : with her hero's ability, Mutant Protectors or Magic Barrier + Defensive Energy flexibilize / accelerate the setup or the drawing in order to increase the odds for an or resource icon.
