The twelfth card is also a Kuriboh from Vrains. This one when you discard it in response to an attack forces the monster into defense mode, which can either stall for a bit or force the enemy into a place they can be destroyed. Its second ability lets it be banished from the grave to help in a ritual summoning. This can be moderately useful in any ritual summoning deck, especially when the ritual spell requires the exact level. It’s a good card if you have ritual monsters, and if you don’t want to use Multiply or Detonate then it should be better than the standard Kuriboh.
