Wraith Form

Wraith Form is an extremely powerful card which has a very real downside. It is extremely effective in hallway fights where you do not expect to be fighting for a long time. When playing out boss fights, you typically don't want to play this card until you know that there are only three terms of combat left. Obviously it is impossible to know exactly when there are three turns of combat left but if you know the boss phases well enough you should be able to guess how long each flight will take you. Playing this card too rarely makes your defends do absolutely nothing and also really reduces the effectiveness of the rest of your blocks, and the silent will not last very long in these situations. The more wraith forms you have the better. If you are constantly intangible, whether or not you can block is completely irrelevant. A well timed nightmare can allow you to have 4 Wraith Forms in your deck with just one card. The other ways of negating the dexterity down effect are by having artifact ignore it or by using orange pellets, which cleanses the dexterity down over time and also cleanses any current negative dexterity stacks. Note that even when intangible you will still be taking chip damage which adds up overtime. For this reason some kind of plated armor effect such as thread and needle can really help you stay topped up.
