Pyroclast mines for metamorph bosses?

Hey there,

I would like to play a shodaw saboteur with pyroclast mines in the next league. But i havent seen the build in any build recommendations for 3.9. Is it a bad idea for a boss league or what am i missing? I like how the build looks.

Thx for your help
Regards

it will be good for bossing,. for clear you can use icicle or arc mines

Thank you for your fast reply!
