“给我十年，我让你见证我的蜕变”，用英语怎么说？

"Give me ten years, I let you witness my metamorphosis."

“给我十年,我让你见证我的蜕变”，用英语怎么说？

这可以有多个表达法如下:
Give me ten years and I'll let you witness my transformation.
或是
I shall only ask for ten years, and you will witness my transformation.
又或是:
If ten year is given to me, then I will let you witness my transformation.
"蜕变”用来形容人英语式不应该直译为蛾蝶的"蜕变”metamorphosis，而是"转型"/"转变"transformation会较为适合。

很希望会对你有帮助。
