Xiao and Toma team?

And why not put Tom C6 on the team with Sao?
I'll explain now! See Toma C6 gives this: "Furning Heart: Obtaining or refreshing Flaming Shield with normal attacks, charged attacks, and FALLING ATTACKS of all instances of the unit over 6 seconds. Gain by 15%." That is, it adds a buff of 15% damage to attacks in the fall, so even the shield is a plus to the benet and there you can add a sucrose battery and here's the team for you. No one mentions it as much as I watched it (if anyone remembers it at all). SOMEBODY can explain to me if it's possible to do this or not and someone can check it. Beg.
