Pros:

BIG BONK

good survivability

can be done on a budget (most likely you will regret it)

Cons:

clunkiest build ever

slow AF

tedious gameplay (it's getting a little better with increased mine throwing speed)

needs a TON of survivability if u dont want to die every 1 minute

99.5% of damage comes from pyroclast mines

These mines are invulnerable only for 2 seconds

Chieftain is the most optimal class for such a build, but you can also choose a Berserker, Jugg, Champ, Inquisitor or even Sabo/Trickster.

Possible improvements: weapon base with higher attack speed, FF/FF War bringer/Aspect of Carnage, Magebloodey, Progenesis, better jewels.

Most likely, the upcoming patch will make big changes to this build (battlemage's cry nerfs will kill it), perhaps I will update it later?, just decided to post it as a meme for now.

Also, you can abuse some weapon swap/snapshot techs with this build, but Chris personally forbid me from doing so.
