Teardrop the Rikka Queen — Ruling

Effetto 1

This card's effect that Tributes a monster on the field is an Ignition Effect that activates on the field. If this card has a Plant monster as an Xyz Material, this effect will be a Quick Effect that activates on the field. (It targets 1 monster in either player's Monster Zone. Detaching 1 Xyz Material from this card is the cost to activate this effect. When activating this effect as a Quick Effect, it can be activated optionally during either player's turn, but cannot be activated during the Damage Step.)

This card's effect that increases its ATK is a Trigger Effect that activates on the field. (It does not target. It must be activated each time a monster is Tributed while this card is face-up in your Monster Zone, including during the Damage Step.)
