Chien Pao

Chien-Pao possesses the coveted-yet-crowded base 135 Speed tier and can even get the jump on its peers with Ice Shard and Sucker Punch, making it a nice revenge killer and late-game cleaner; Ice Shard in particular stands out in a metagame with numerous fast Dragon-types. Its Dark / Ice STAB combination matches up well into defensive staples like Necrozma-DM, Arceus-Ground, and Ting-Lu, and Icicle Crash can also potentially flinch through otherwise solid counterplay like Ho-Oh. However, Chien-Pao is exceedingly frail and entry hazard-weak, making getting it onto the field safely, let alone multiple times, quite difficult. This also means it offers exactly no defensive utility to its team. Due to the low Base Power of its moves, it is also relatively weak by Ubers standards without finding a turn to use Swords Dance, which is hard to find due to its frailty. Chien-Pao is also scared to death of Zacian-C, which outspeeds it and resists both STAB types. Kingambit also provides heavy competition, as it has substantially better bulk, resists Stealth Rock, and boasts an even stronger Sucker Punch late-game, at the cost of much worse Speed. Ultimately, Chien-Pao's Speed, priority, and STAB combination make it a noteworthy cleaner, but it still finds itself more limited compared to metagame staples like Koraidon and Zacian-C.
