They way you would for any other move. Just choose the move from the attack screen and your Pokemon will attack. (By the way, False Swipe can't be used in the field)
gliscor can ;p
To teach Smeargle False Swipe you need to find a Pokemon to fight that knows False Swipe. Make sure Smeargle has at least one copy of the move Sketch. During the battle with the Pokemon that knows False Swipe use Sketch after the opposing Pokemon uses False Swipe. If done correctly your Smeargle's Sketch should permanently turn into a False Swipe.
scyther at least.
false swipe is learned by the following Pokemon upon levelling:scythernincandazangoosefarfetch'dgalladegrovylecubonehowever, false swipe is also a TM. this makes the move available to other Pokemon as well (kriketune, weavile, parasect, kingler, anorith, etc).
Put a Dark-type Pokémon with False Swipe (I recommend Absol) at the front of your party. Use False Swipe until Mewtwo is at 1 HP. Start throwing Dusk Balls.
Use false swipe to weaken to 1hp, then afflict paralysis.
None and besides false swipe is a bad move.
get apokemon that know false swipe to get its hp low or use a master ball
master ball, paralyze and block, false swipe and random balls
you can catch it by teaching a Pokemon False swipe. The first time you encounter it and you use a move, it will flee. next time you encounter it, paralyze it or put is to sleep. The moves charm and thunder wave work best. also sweet kiss. Than use false swipe and a quick ball.
only one. Use sleep and false swipe with arena trap and then it's done :-)
arena trap ability or mean look can keep it in place then use false swipe to lower its HP
