Sigil of valor gamebreaking bug

Sigil of valor completely heals any creature any time it changes based on adding or losing a creature. You can take an 11hp creature to 1 then tsay Rhett have only an 8/8 creature. With sigil of valor is an 11/11. Take it to 1 hp so its 11/1. They cast a second creature and it fills to full making 8/8 then recalculated the bonus to +2/+2 so its 10/10. For a 3 count support this is impossible to remove without your opponent abusing the **** out of it.
