plus the cost of the creature that earthbends available.
Steps
Cast the earthbending creature by paying its mana cost.
When you cast that spell, you lose 1 life and create a 2/2 artifact creature token.
The earthbending creature enters as an artifact land creature due to
Biotransference and
Toph.
When that creature enters, it triggers itself and
Blasting Station.
Resolve that creature's earthbend ability targeting itself, causing that creature to become a land creature with haste, putting at least one +1/+1 counter on itself, and creating a delayed triggered ability.
Resolve the
Blasting Station trigger, untappping it.
Activate
Blasting Station by tapping it and sacrificing that creature.
When that creature dies, the delayed ability from step 4 triggers, causing it to return to the battlefield tapped as an artifact land creature.
Repeat from step 4 any number of times.
Resolve all activated abilities from
Blasting Station.
