Level 100 Statistics (see level 5, 50, 100)
This pretty flower has been blessed with a great Special Attack stat, two useful abilities in Chlorophyll and Solar Power, and a pretty good movepool to take advantage of. Although she seems great at first glance, you'll notice her poor Speed and defensive stats make it difficult for her to sweep and leaves her vulnerable to priority moves. Her lack of useful supporting moves is also a disappointment; her support movepool is so shallow, she is even forced to use the horribly unreliable GrassWhistle instead of Sleep Powder. With the correct teammates and/or field effects, Sunflora is a decent offensive Pokemon; just play it safe, she's as delicate as a rose.
Although Sunflora looks like "just another Chlorophyll user," she has higher Special Attack and a better offensive movepool than most of them. When the weather is sunny, Sunflora has enough Speed to outrun base 95 Pokemon and base 105s with a Timid nature. SolarBeam is used for STAB, as the sun removes its charging turn, Hidden Power Fire is used to hit other Grass-types and gains a boost from the sun, and Earth Power provides coverage against Fire-types. Grass Knot can be used for STAB outside the sun and deals a lot of damage to heavy opponents.

This set takes advantage of Sunflora's alternative ability Solar Power, boosting her Special Attack to insane levels. This does come with its drawbacks however. Using a Life Orb when the sun is active causes Sunflora to lose 22.5% of her health per turn, making her extremely frail, and giving her little time to sweep. Leaf Storm is an immensely powerful attack coming from 105 base Special Attack, boosted by Life Orb and Solar Power, and gaining STAB as well. Earth Power is used to hit Fire-types such as Houndoom, Blaziken, and Magmortar on the switch, while Hidden Power is used to hit opposing Grass-types. Synthesis is used to recover Life Orb and Solar Power recoil, and also benefits from the sun by restoring 2/3 of Sunflora's health.
Team Options & Additional Comments >>>
Sunflora has a pretty good movepool, though half of her attacks are rendered useless by her mediocre stats. Encore can be used against slower Pokemon trying to set up stat boosts, giving a teammate extra time to set up. Leech Seed can be used alongside Substitute to restore Sunflora's health, though her low Speed makes it difficult to pull this off before she gets KOed. Endeavor can be used with a Focus Sash to severely weaken the opponent, but a lack of priority makes it difficult to finish them off. Growth can be used to raise Sunflora's already high Special Attack. GrassWhistle can put an opponent to sleep, just beware of its shaky accuracy. Light Screen raises Sunflora's Special Defense and supports her teammates, and Sludge Bomb hits other Grass-types super effectively, though it provides poor coverage. Swords Dance can be used alongside Seed Bomb and Return, but Venusaur is a much better user of this strategy as he has access to Sleep Powder and Earthquake.
Checks and Counters
Most Flying-types can take on Sunflora with ease as they resist her main STAB and have super effective attacks to KO her. Moltres, Swellow, and Altaria are just a few examples. Chansey and Clefable can take on any Sunflora thanks to their massive HP and Special Defense stats, access to status moves, and reliable recovery. Golduck can cause problems with Cloud Nine as he outruns Sunflora without her Chlorophyll boost and has access to Ice Beam to hit her super effectively. Specially defensive Weezing is immune to Earth Power, has a resistance to Grass-type attacks, and has Sludge Bomb to dispose of Sunflora. Specially defensive Arcanine is another good option as he can survive Earth Power, has a resistance to Grass-, Ice-, and Fire-type attacks, and has STAB Fire-type attacks to scorch Sunflora. Although Sunflora is fast when her Speed is boosted by Cholorophyll, she's still too slow to beat Pokemon such as Alakazam, Dugtrio, and Sceptile, all of whom can hit Sunflora on her frail defenses and KO her. Finally, Sunflora's poor Defense leaves her vulnerable to physical priority moves such as Sucker Punch and Ice Shard, so take advantage of them when you can.
