This clever loop turns Deathbringer Thoctar into a self-sustaining artillery piece by capitalizing on damage triggers and counter magnification. By casting Strength of Will on Deathbringer Thoctar, you grant it indestructible and a massive growth trigger whenever it takes damage, letting it safely shoot itself to trigger its own ability. Meanwhile, Benevolent Hydra acts as the ultimate amplifier, turning every single counter placed on Deathbringer Thoctar into two, which creates a net surplus of counters each cycle. This allows Deathbringer Thoctar to endlessly fuel its own damage ability while growing infinitely larger, leaving you with as many +1/+1 counters as you want and an infinite amount of damage to close out the game.
