Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
dragapult and chien pao is your main lead with team. sneasler and indeedee usually come in the back. if you want to use tr, I reccomend you bring indeedee and one other pokemon unless you expect a very slow game.
if the opponent has too good of speed control, you can lead iron hands and farigiraf, trick room it up, and you're great. the same lead snuffs opposing TR effectively as well.
what do you do when you swap in sneasler? just attack with both, protect one, or swap to indeedee to boost your sneaslers speed. ineedee also helps stop sucker punch which usually makes dragapult feel useless unless you tera.
the general basis of the team when starting was indeedee sneasler, the two make for a good opener in certain situations, but mainly you should use them in the back. Indeedee is the best switch in on the team, and Sneasler loves to come in after KO's to your side to create offensive pressure.
Welcome to my team, Callout City.

here's the link to my team I recently got into masterball with. not particularly high, but I came from greatball 8 all the way to masterball undefeated and I believe that speaks to the value of the team.
