White Serval is, to put it bluntly, busted. She is the best Funny DPS in the game, with an astronomical attack stat only rivaled by Fennec Fox (Lovely), while still having respectable defense bases. Her miracle has an extremely high damage percentage, even among other single-target miracles; it is highly recommended you max it as soon as possible to unlock its tremendous damage potential, not to mention its Beat Miracle+ flag. The additional status effects are almost immaterial in comparison, but certainly do not hurt to have.
Her long-lasting Beat debuff will reap great rewards for your team's sustained damage output; its duration also means there is less pressure for you to have White Serval attack first in situations where it would force you to use less advantageous flags. Her Miracle Trait's revival effect, while rare and notable, is only situationally useful and attempting to strategize around it would be extremely difficult; however, it is most certainly still worth getting due to it increasing her damage even further and addressing a potential weakness to evasive enemies.
Her Unique trait is amazing, giving her resistance to 2 of the game's 4 miracle-blocking effects (the others being Stun and Freeze) and very beneficial regeneration effects depending on her health. This is a set-and-forget passive for the most part, requiring no direct strategy from the player; the only unlikely exception would be if White Serval were 3 or less MP from her Miracle and you had the choice of healing her or not.
White Serval's most infamous ability by far, however, is her Standby. First witnessed by players in the kit of the unobtainable Serval in Arai-san's Diary, the ability to infinitely trigger high choruses for free has immense benefits. While the extra DPS gained from White Serval hucking an extra ~10K damage per turn is obvious, its main appeal is giving your team higher damage multipliers, bonus MP or bonus Try charge depending on the flags used (and, of course, Extra Helpings). Do note, however, that using this recklessly against Celliens with MP bars can result in your team taking more damage or debuffs than you may be ready for; at any rate, White Serval can still pay dividends without it.
Sand Cat (Funny) synergizes extremely well with White Serval, as the former's Miracle deals more damage to enemies with Bravado. Hippopotamus can provide White Serval with Stun resistance, meaning that White Serval's miracle can only be blocked by Freeze. Friends that inflict CC can also work to offset the higher MP gains enemies enjoy from White Serval's standby; Atlantic Puffin, Sheep and Shoebill are all good choices.
