A player, 29 June 2012
I know that if I use Den of Iniquity during my action phase, I cannot declare an attack during my attack phase. However, if I declare an attack during my attack phase, does that mean I may not use Den's ability during the action phase granted by Twisted Fate?
I guess I'm asking if Den's restrictions lasts from when I announce the action until the end of my turn or if it is applied retroactively.
Den of Iniquity
Political Limited: Bow this card and target another player's dishonorable Personality: His controller loses Honor equal to his base Personal Honor, or 3, whichever is lower. You may not declare an attack this turn.
Twisted Fate
Until your Events Phase three turns from now begins, there is an additional Action Phase each turn which occurs between the Dynasty and End Phases.

The Den's restriction only applies from the moment it is used. It does not check to see if you've declared an attack previously.
