While Sora isn't reliant on her Hyper to win, Extraordinary Specs still allows her to make powerful plays in the later stages of the game. Bringing cards like Nice Present increases the odds of drawing it while President's Privilege can mitigate its high cost.
Combining Extraordinary Specs with Final Battle or Accel Hyper will almost guarantee that Sora will KO her opponent but she'll be left at a huge disadvantage if this expensive combo gets countered. Be weary of a possible Shield Counter and characters with powerful battle Hypers.
Because Extraordinary Specs guarantees a 6 for her movement roll it's important to be mindful of the possible panels Sora could land on when she has access to her Hyper, especially if the Boss is low on HP or if Sora has the opportunity to finish her final Norma by landing on an opponent's Home. Be aware that Ice, Goo and Windy Enchantment can change the number of panels that Sora will move.
Party Time can help Sora set up Extraordinary Specs as it'll put all opponents in range of her Hyper. Even if used by someone else, depending on the move order she could still use her Hyper to attack an opponent that moves before her while protecting herself from opponents that move after her.
Assault can be devastating for an opponent that lands on it while Sora is under the effect of Extraordinary Specs but this is difficult to set up.
Sink or Swim can be combined with Extraordinary Specs to take out a low HP opponent with relatively little risk and a potentially high reward.
Sora's biggest threat is her Hyper but it can be played around by staying behind her. High ATK characters can take advantage of her low HP and try to take her out without exposing themselves to her Hyper and even non-aggressive characters should consider attacking into Sora to prevent themselves from moving in front of her if they're afraid she could use Extraordinary Specs.
Since Extraordinary Specs guarantees a high attack roll, cards that raise your DEF are preferred since successfully evading is very unlikely. Cards like Shield, Rbits and especially Shield Counter can be used to survive against the Hyper.
Cards like Brutal Prank and Flamethrower can be used to deny Sora access to her Hyper, making her less threatening in the late game.
While Scrambled Eve and Gift Exchange can be used to steal Extraordinary Specs from Sora, it's possible that it might end up in the hands of an even scarier opponent and with no way to tell who could have access to the powerful Hyper the risk of using these cards might not be worth the reward.
