Activate Selvala by paying and tapping it, adding at least 1.
Activate Woe Strider twice by sacrificing Selvala and Slimefoot and Squee.
Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling, returning it and Selvala from your graveyard to the battlefield.
When Slimefoot and Squee enters the battlefield, it triggers, creating a 1/1 Saproling creature token.
Repeat.
This clever loop sets up an endless cycle of sacrifice and rebirth by leveraging Slimefoot and Squee’s ability to pull itself and another creature straight from the graveyard, fueled by the massive mana-producing potential of Selvala, Heart of the Wilds. As Woe Strider acts as the reliable sacrifice outlet to feed the graveyard and smooth your draws with scry triggers, the Saproling token created upon Slimefoot and Squee's entry provides the exact fuel needed to pay the revival cost. Meanwhile, Frostcliff Siege quietly supports the board with a Temur or Jeskai mode that grants valuable keywords and card draw, ensuring your explosive loop comes with plenty of tactical flexibility.
