Getting back to Shakugan no Shana i can foresaw some good matches:

* Shana VS. Nanoha: The Ace of aces have superior firepower but Shana is arguably faster than her on the air an even faster on foot, her sword is unbreakable and, if provoked enough, can even the ground in firepower with flames powerfull and big enough to engulf entire city blocks, she also posses Tempa Jousai as a last resource which consist in summoning Alastor, basically a flame god, to the mortal realm, we're talking about someone around five-to-ten times bigger than Voltaire and hundred times more powerfull(blows up a floating city just by appearing). But Alastor aside it will be an exciting and balanced battle due to Nanoha's genius in battle.

* Margery Daw VS. Fate Testarossa: Margery is a hunter, she's fast, feral and predative in her fightstyle which make a good contrast with Fate's elegant assasin-like attack pattern, Margery is proud to have various mult-fire spells as also is good with incantations to achieve various effects on the battlefield which are akin to her Huntress status and will find a worthy opponent in Fate who is a very adaptable mage able to fight in all ranges and almost all terrains.

* Master of the Throne, Hecate VS. Hayate Yagami: This is a no brainer, both ominious squishy wizards with unholy gargantuan firepower and a more "supporting role" on the battlefield as also both being important/sacred figures to other people.

* Wilhelmina Carmel VS. Signum: Two veteran and clever warriors with a battle-forged stoicness and lots of experience, The Blazing General will prove to be a strong foe to the Master of a thousand Ribbons due to her ability to incinerate Wilhelmina's main weapon, still, Wilhelmina already showed us how well she can deal with flaming swordwielders in her fight with Sabrac. My guess is that both will first try attempts to neutralize the other as quickly as possible, then realizing that the opponent is not an easy prey and in round 2 they will start to analyze each other in search of a weakpoint or an opening. It can go both ways: Signum burns her way to Wilhelmina and fulminates her with a direct sword-slash or Wilhelmina manage to see through Signum attacks and traps her in a myriad of ribbons while crushing her until asfixiating the Knight of the Sword before any possible comeback.

* Serpent of the Festival, Sakai Yuuji VS. Tohma Avenir: The battle of the superpowered emo-kids xD! It will depend if Tohma's Zero Driver powers are enough to seal the Serpent of the Festival, if not, it will be just another easy curbstomp for Yuuji.
