Obosh, the Preypiercer

Heartless Hidetsugu

Glacial Chasm

How it works

1. Tap Heartless Hidetsugu to deal opponent life equal to their lifetotal.

This devastating brew relies on Glacial Chasm to completely shield you from all damage, neutralizing the downside of Heartless Hidetsugu's tap ability. Once you activate Heartless Hidetsugu, it cuts every player's life total in half, but thanks to Obosh, the Preypiercer sitting on your battlefield—whose odd mana value safely doubles odd-source damage—the damage dealt to your opponents is doubled to their exact life total, instantly obliterating them while you remain safely untouched.
