added trumping to the glossary as such:
Trump - After playing a card, often another card is played on top of it, negating the effect or ability of the first card. This is called "Trumping" and is often confusing for the new card player. When something is Trumped, the last card played (the one on top) is active and the activities of the last card are not used. When something "Can not be trumped" then that cards effect or ability goes on no matter what any other cards say. The card that "can not be trumped" has the dominant authority in the final outcome of the turn resolution.
