A good example of someone attempting to use the "Unbeatable Trick" is the Crane Kick from Karate Kid. It is the "move that when done properly, cannot be countered." Yet, if you've watched to movies, every time Daniel-san tries to use the move in later movies, the bad guy counters it and Daniel-san must now use his new "Unbeatable Trick" to overcome his new foe.
If it comes up in a game, I think the response is generally the same. If PCs are too heavily relying on a certain trick, the DM usually pulls some monster or effect that makes the player's little trick work not so well.
For example, if the characters use Tenser's to float over hazardous terrain, the smart DM puts in geysers, or inserts a terrain-immune creature that tips those on the disc into the terrain. If he's really smart, he puts a mcguffin item the characters need under the terrain. Kudos if he gives the bad guys their own Tenser's to conduct a fight over the surface on the discs...
In the end, there are so many ways for the DM to gently or firmly direct the players so that "Unbeatable Tricks" aren't. A lot of times, it doesn't even have to be a permaban - one or two thwartings of a "Unbeatable Trick" is often enough to make most players back down on using it.
