The all-important card! NEGATE is arguably one of the most useful cards in the entire game. If you are familiar with the card game "Monopoly Deal", you would quickly see the similarities between NEGATE and "JUST SAY NO". Every tool card can be negated, including NEGATE itself! NEGATE can be used by any player at any time. You don't have to use it during your turn!
What it does:
It renders the tool card or its effects useless. Where the tool card affects only 1 player, using NEGATE renders the tool card useless. Where the tool card is a "Multi-player effect" tool card such as RAINING ARROWS 万箭齐发 or HARVEST 五谷丰登, using NEGATE only renders the effect of the tool card useless on 1 player.
NEGATE [Kingdom] works the same way with the exception that the effects of NEGATE affect all players that belong to the kingdom being negated. Effectively, you can negate up to 6 players in a 12 person game with just this one card!
How to use it:
Before a tool card takes effect on a player, you can use NEGATE on that tool card. If that tool card is not NEGATE, the effect of that tool card on a player is neutralized. If that tool card is NEGATE, neutralize it completely.
The phrase 无懈可击 is also not from Romance of the Three Kingdoms. In fact it dates even further back to what is known as the "Spring and Autumn Era 春秋时代" in the Eastern Zhou dynasty 东周朝代, pieced together within the writings of the famous Sun Zi 孙子. Yes, the dude who wrote "Sun Tsu's Art of War 孙子兵法". The literal meaning of 无懈可击 is "to have no weakness, no carelessness, such that the enemy cannot exploit us".
