Does her ability work with Time Warp? I don't think so, because "undo" is not the same as "cancel". But I'm not a native english speaker, so i'm not sure.

Hi @django042 'cancel' and 'ignore' are specific game terms, so yes, Time Warp does *not* work with Diana Stanley's reaction ability.

Edit: fuller explanation - Time Warp isn't cancelling or ignoring anything... it's treating the action as though it never happened and going back in time... It's a strange card, rules-wise, but yeah, it's not an ignore or a cancel.
