Activate Goblin Bombardment twice by sacrificing another nontoken creature you control and Slimefoot and Squee.
When the creatures die, Pitiless Plunderer triggers four times, creating four Treasure artifact tokens.
Resolve the Goblin Bombardment abilities, dealing 2 damage to any target.
Activate the Treasures by tapping and sacrificing them, adding 1.
Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling.
When the Saproling dies, Pitiless Plunderer triggers twice, creating two Treasure artifact tokens.
Resolve the Slimefoot and Squee ability, returning it and another creature from your graveyard to the battlefield.
When Slimefoot and Squee enter the battlefield, it triggers, creating a 1/1 Saproling creature token.
Repeat.
This clever loop turns graveyard recycling into an endless engine of destruction, fueled seamlessly by the synergy between Slimefoot and Squee and Goblin Bombardment. As creatures hit the graveyard, Pitiless Plunderer converts those deaths into Treasure tokens to pay for Slimefoot and Squee's recursion ability, ensuring you always have the mana needed to bring everyone back. Meanwhile, the presence of Drivnod, Carnage Dominus supercharges your death triggers by doubling every single Plunderer payout, turning a modest sacrifice loop into an explosive cascade of extra mana, tokens, and direct damage.
