<p>Jynx can immediately get the game going in your direction. By using Trick on the opponent's lead, usually locking them onto Stealth Rock or another support move, you force the opposing lead to switch out. As the opponent switches out, stuck with a Choice Scarf, you can use Lovely Kiss to incapacitate the another Pokemon. Now, with two members of the opponent's team already severely damaged by sleep and a Choice Scarf, you can start firing off the attack of your choice. Ice Beam is your strongest move, benefiting from STAB. The final move comes down to what threatens you more. Psychic is your strongest move against Poison-, Fighting-, Fire-, Water-, and Ice-types. This, however, leaves you helpless against Steel-types so Focus Blast is another very acceptable option. </p>

<p>It may not always be beneficial to use Trick as your first move. If the opponent doesn't often use a support move as their first move, it may be better to either use Lovely Kiss or to switch out. Later in the game, if you still have your Choice Scarf, you can either disable the opponen't walls by Tricking a Choice Scarf onto them, or Jynx can even become a reliable Revenge Killer.</p>
