IM GOING FOR PYSHICAL ATTACKER DRAGONITE
Dragonite @Yache berry/Focus Sash (MOSTLY USEFUL FOR SINGLE BATTLE)
Trait : Inner Focus (Multiscale is a good option tho.)
Nature : Jolly (+Speed,-Sp.Attack)
EV: [252 attack / 252 Speed / 4 Sp.defense] or [252 Attack / 100 Sp. Defense / 100 Defense / 56 Speed]
-Dragon Claw/Dragon Tail
How useful the moveset:
+Dragon dance for Attack and speed Boost for around 1-3 turn
+Dragon claw or Dragon tail for pyshical Stab moves,But I recommend Dragon claw rather than dragon tail,dragon rush because bad Accuracy,Outrage Because Confusion which is bad or Dragon Pulse Because Dragonite is mostly a pyshical Attacker.
+Iron head cover All dragonite weakness being Fairy type,Ice Type and Rock Type so you dont waste the last slot
for another coverage move,Plus Iron head has 80 base pyshical attack and 100 accuracy,so its pretty good.
+For the last one...Its whatever you want,Since all the other move already cover Dragonite so,You can add
Earthquake for Strong Pyshical Move plus Add some coverage,Hurricane,Waterfall ,The elemental punches or
Substitute so you can have time to use Dragon dance.
You Can Obtain Move In :
-Dragon Dance (Level 61)
-Dragon Claw (TM 02) or Dragon Tail (TM 82 or Move Reminder but you dont want to waste heart scale if you can get from TM)
-Iron head (Move Tutor)
-Earthquake (TM 26) / Hurricane (Level 81) / Waterfall (TM 98) / Fire,Thunder and Ice Punch (Move Tutor) / Substitute (TM 90)
Sorry if this is too long ! Hope this set will be useful!
