Activate Selvala by paying and tapping it, adding at least 1.
Activate Blasting Station by tapping it and sacrificing Selvala.
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 and Selvala enter, Slimefoot and Squee triggers once and Blasting Station triggers twice.
Resolve both Blasting Station triggers, untapping it.
Holding priority, activate Blasting Station by tapping it and sacrificing Slimefoot and Squee.
Resolve the Slimefoot and Squee trigger, creating a 1/1 Saproling creature token.
When the Saproling enters, Blasting Station triggers, untapping Blasting Station.
Repeat.
This loop turns the recursion engine of Slimefoot and Squee into an infinite damage machine by leveraging the mana production of Selvala, Heart of the Wilds alongside the self-contained sacrifice and untap triggers of Blasting Station. Every time Slimefoot and Squee and Selvala are brought back from the graveyard, the resulting creature entries repeatedly untap Blasting Station while the newly created Saproling token and the commanders themselves are fed into the station for lethal damage. Meanwhile, Tannuk, Steadfast Second sits comfortably on the board, ensuring your reanimated threats can immediately act if needed while providing alternative casting options through warp.
