Cirno, still running towards her opponent fails to notice the force wave speeding towards her in time. She tries to jump over it, but her feet get caught in the attack, making her fall over. However, she manages to catch herself back up by creating a frozen pillar from her hand, which was "raised" towards the ground, to the ground. [this sentence looks pretty iffy....]
Still upside-down, she shouts out, "Alright! Now it's time for me to counter attack!" Ice spawns from the waffer blades, pushing them in cirno's direction. The ice then breaks off, effectively launching the blades towards her.
" Limit card! Meteobalde Rain!" * she takes out her two chocolate edges and throws them in as hard as she can in the sky. She then catches her waffer blades and does the same, the blades glisten in the sky as they keep travelling upwards. She then sends her two remaining blades too.
Having reached the peak of their flight, ice forms on the hilt of each blade, extending towards the other blades. Icy lances then send each blade flying at high velocity towards Gamma.
In a matter of seconds, Gamma gets bombed by a flight of frozen swords.
[think meteorain but with ice swords, or think archer emyia from the fate series's attacks, if instead of firing swords with his bow he fired them in the sky and they then fly towards the enemy from there. Also, keep in mind I come up with these things on the fly, they're prototypes they won't be as such in the final game]
