The phrase "this card" in the second-to-last sentence refers to the terrain card, not Master's Tactics. Rules Archive, August 18, 2007, p. 25
Will not override an effect that prohibits you from playing terrains (e.g., Secluded Ravine). [DW, 28 July 1998] Rules Archive, August 18, 2007, p. 25
Will make the terrain uncounterable by generic card-countering effects (e.g., Mujina Tricks). Master's Tactics can usually be countered instead, however. Rules Archive, August 18, 2007, p. 25

Q: Any number of Actions which count as a use of the Tactician trait - default (the actual Action is in the rulebook not on the card), Superior Strategist, Master's Tactics, etc - are not performed by the Tactician.
A: The Gold Edition rulebook will define discarding for a Tacticial Force bonus as an action performed by the Tactician. Jeff Alexander, "replies to the 6 June digest", 10 Jun 2001
Q: Hiya,
My first question concerns the card Master's Tactics.
Master's Tactics reads "All effects that would prevent this card [terrain] from taking full effect are negated."
If I played Master's Tactics with the Terrain Battle of Quiet Winds, would I be able to target an opposing personality with Kitsuki Kaagi's Journal attached?
A: No. The Journal does not negate or prohibit effects, it restricts targeting. Jeff Alexander, "Rulings for 12-13 April 2001", 19 Apr 2001
