Mix some or all of these double-edged actions, modifiers, and reactions into your Runes of Zun deck. As part of the theme, there's a reverse Boost-like card called "Reduce," which can be used to modify any card that allows Boost by lowering effects and even flipping them completely! Most of the other cards have something good and something bad, so by adding modifiers like Reverse and Boost, you can twist them into double-good and double-bad effects.
