Spell 13: Dragon!Wizard curbstomping Minotaur. While terrifying, its still undoubtedly awesome.
Trixie gets another one by actually standing up to Dragon!Wizard to save Twilight's life, managing to keep him busy long enough for Haru to regain control. Note, this is after witnessing Dragon!Haru completely demolish the supercharged Minotaur Phantom.
Spell 15: Phoenix gets one by beating the hell out of Haru. Haru also gets one for managing to at least land some hits on Phoenix, even if he's ultimately not strong enough to take him out.

While also absolutely disgusting, Gremlin effortless evading both Beast and Wizard while killing Hellhound and Minotaur, and killing a superpowered Harpy in seconds counts.
The team up with the ToQgers. Especially them using their Imagination power to turn Wizard into Wizardragon for the Finishing Move.
Spell 29: Applejack and Rainbow Dash are playing horseshoes against Haru and Kosuke. They win. By a lot. Even when Haru cheats with his magic.
Spell 34: Wolzard quickly knocking Beelzebub on his butt after quickly figuring out the trick to his Playing With Portals ability.
The author deserves props for how balanced the two series end up being. The series comes off less as a crossover and more as a single ongoing story, combining the Wizard and MLP stories together. Often canon episodes of one will be interlocked with the basic idea of others, or Phantoms are worked in. And both sides aid one another in their various struggles. Considering how many fanfics fail at doing this, it's quite impressive to see one where both sides of the crossover are well depicted and balanced.
