Why Summon the Titan Soldier?

I'm not asking you to integrate forever. I'm not a devil. But what does it mean to go back to deck fusion? Why is your fusion deck still T0 moving? It's not your turn yet, right? If this continues, You fuse three times in one round, six times in two rounds, and finally become a nine-tailed demon fox. As a titan, I may have to defeat you. Real.
