indestructible counter moved by nesting ground doesn't give indestructible



I have a [[Toralf, God of Fury]] with a indestructible counter that I put it in there with a [[Nesting Grounds]] from a [[Solphim, Mayhem Dominus]], then some turns later my opponent cast a Fumigate and my Toralf got destroyed

Reproduce the reported sequence with Toralf, Solphim, Nesting Grounds, and Fumigate, then trace how the indestructible counter is moved and applied. Compare the resulting behavior with the expected indestructible rule and add a regression test for the sequence. Done means Toralf survives Fumigate after the counter is moved.
