Alchemize

Alchemize is a unique and powerful skill that I would rarely skip but often loses out to better alternatives, particularly rare cards. This card has considerable synergy with Burst. At higher ascensions, you're only offered two potion slots unless you take Potion Belt which means you don't get to store up a great amount of potions for important elite or boss battles. Obviously, never take this if you have Sozu. On the other hand, Toy Ornithopter means consistent healing which is important to the Silent. If I find I have a lot of energy, I take this card as I know I can afford to play it without taking too many risks, since the potion that you get is always random.
