When playing Temmo from hidden (which costs 0), do you still need to recycle 1 blue rune?

Ruling: When you play cards from hidden, they cost 0 and you follow the text after "hidden" on the card's description instead of the original card's cost. You do not need to recycle the blue rune.

Nuances:

• The hidden cost completely replaces the original cost, including any additional costs like recycling runes
