Ye Hua, Crown Prince

This spell may not be countered.
Indestructible.
As long as your devotion to a colour is less than
five, Ye Hua is not a creature.
Creatures you control gain Haste and Vigilence.
If Bai Qian is under your control, all damage
dealt to them are halved (rounded down) and
all damage they deal are doubled (rounded up).
Sacrifice Ye Hua, regenerate all creatures you
control.
