A: - First off, yes, you can play Null on Maddening Compulsion and avoid it completely. - In fact, any card that "you can play when it is not your turn" may be played even after Maddening Compulsion takes effect so long as it is indeed played out of turn. For example, you can play Detonate on a Maddened Hex in front of another player. You could also play HEX•HEX - but only if you are not the current Intended target of the Maddened Hex.
- BUT if you are the Intended target of a Maddened Hex, you must pass it in the named direction. If you can't pass the Hex in the stated direction by any means, you are HEXED.
- 'By any means' includes Duck, Boost, Called Shot (if you name the appropriate player) or any other card that moves the Hex in the correct direction.
- Twain is legal to play because it does pass the Hex in the named direction. (Yes, the duplicate does move in the opposite direction momentarily but it does not go off. The Maddening condition was satisfied for both the original and the duplicate when Twain was played.)
- In a three player game, Deflect Across may be used because it does fulfill the 'by any means' condition. But only in a three player game.
- Other card effects are trumped by Maddening Compulsion. Dismiss and Hex Sign which normally would cancel the Hex can not be played.
- Yes. You can play Maddening Compulsion on a Maddening Compulsion, even if it reverses the direction the Hex travels. Why? It supersedes all other effects.
- Is Fate legal? Yes. The card allows you to get another AND THEN respond to the (Maddened) Hex. It fulfills the 'by any means' wording of Maddening Compulsion. (NOTE: the last FAQ answered this incorrectly as a NO. Sorry, 'bout that.)
