you dont need pictures to post a good rmt, i'm actually glad you didn't cause if you had i'd be annoyed that you'd think that's more important in your "competitive pokemon career" than actually explaining your team's synergy
but first things first—you will soon find that this team is way too frail to compete in today's metagame. np passing togekiss worked for a little bit two years ago but is less effective now because it will get taunted by what we call "suicide leads"—lead pokemon that have focus sash and taunt and are bent on setting up stealth rock and nothing else. aerodactyl and azelf are the main perpetrators. you'll square off against these or steels like metagross and jirachi who won't let you do anything either, jirachi gladly either going for an ironically better flinch chance than togekiss can boast with choice scarf iron head or tricking that choice scarf onto togekiss, stopping it from passing anything.
if togekiss is able to pass a boost to one of your sweepers you're going to be disappointed pretty soon there too. you're aware of technician bullet punch enough to take the next step and think of how little scizor cares about alakazam no matter how many boosts it gets—this is the main reason that nobody really uses alakazam anymore, others being general frailty, neutering at the presence of tyranitar and pursuit (without life orb [an unusual item for zam] focus blast rarely kills even a min/min hp/def tyrantiar) and redundancy of its one DP niche—trick scarfing. if you're going to continue using this team you should probably drop zam first, as its defenses are thinner than the paper on which it seems to work at first.
then with starmie...dont use specs if you're going to use this as a special sweeper. if anything, you can actually use specs, but replace psychic with trick to be a little more threatening. starmie works as a special sweeper or can work mainly because it resists scizor's bullet punch, otherwise it would be in much the same boat as zam as an actual special sweeper.
the rest of your team actually looks good because they're solid pokemon—it seems you know what scizor can do in dppt and why it is good, and may have stumbled upon why flygon and especially that flygon is good—resistance to stealth rock and roost. but your actual central strategy is what is going to need work...it's good that you actually have one and havent just thrown pokemon together, very good actually because new members usually tend to do that and it's annoying. but kiss will be hard pressed to pass NPs in plat and if you wanna go the route of "frailty" i would suggest a timid life orb lucario with aura sphere/vacuum wave/dragon pulse/hp rock but that's kinda gimmicky on paper and i just made it up and am rambling now and also love lucario "but" +2 vacuum wave deals with heatran which popularly carries a scarf and hp rock deals with gyara and zapdos (heat wave) as well and you'll be able to pass to luke cause it covers kiss's weaknesses and this is where i finally use a period.
