Once summoned, you can choose not to activate the effect of opponent sending 1 monster to the graveyard, to avoid Enemy Controller tribute take counterplays, and preserve your Dakini. Choosing this option does not put you in a huge disadvantage because of Dakini’s effect of allowing all ritual monsters on your field to do piercing damage. In this scenario, even your ritual monster(s) piercing attacks will do some considerable damage to opponents’ Life Points, and may also force them to reveal their face-down cards.
