There I was, working on a plan to marry banding, flying, and Guard Gomazoa, so white had to come into the mix. Not everything is a perfect fit, but I needed a little fetching (see Squadron Hawk) and just plain base creatures (see Zephyr Sprite, Lantern Kami) just to make up the weight at the lower end. Azorius Ploy and Lyev Skyknight made for useful tools to turn on the opposition at an appropriate time. Gossamer Chains can harass whatever is worst, and a couple copies of Holy Day can save my bacon. The presence of Goldenglow Moth is a result of having banding. If I can toss the damage onto something else while still gaining life, why not do it? The 11/15/10/4 curve is not bad, and it averages only 2.18. The name refers to the way refrigeration systems work, using chemicals that change states between liquid and gas.
