A New Alliance Invest : Draw a card. (Increase the Gold Cost by the Invest cost to get the effect, once.) Political Open: The abilities on two target Dynasty or Fate cards (in play) cannot be used.
Come One at a Time While there is exactly one defending Personality here, he has the ability, "Repeatable Battle: Challenge a target enemy Personality. Destroy the loser" and each player has the ability, "Repeatable Battle: Move home your target attacking Personality. Bow him as he moves." Battle: Destroy a Terrain (if able). Put this Terrain into play. Take an additional action granted by it.
Does new alliance prevent the use of created abilities, even those created after its use?

A New Alliance only affects abilities that are on the card at the time it (ie, A New Alliance) is played.

I am sorry, but I do not understand the reasoning behind this answer. Simply because there was no reasoning given.
My logics tells me that A New Alliance does not shut down abilities CURRENTLY present on the card. It says directly "you know, boy, those 2 cards you can consider blank for the rest of the turn". It does not say "remove abilities currently printed on them".
Can I get a more precise explanation?

I was extending from this ruling on Again!
