Certain game processes and effects can put cards underneath (下 shita) your LRIG and SIGNI on the field.
Whenever you grow a LRIG or put a SIGNI with Rise onto the field, all of the cards it was placed on remain on the field underneath it. Additionally, certain effects such as those of U, Natural Element, §Poseidona§, Raging Ocean, or MIRROR can place cards underneath your LRIG and SIGNI. Cards underneath your LRIG can be put into your LRIG Trash to pay for Exceed costs.
Cards underneath your LRIG and SIGNI are not considered to be LRIG or SIGNI, so they cannot be affected by effects that designate LRIG or SIGNI. In addition, their abilities are ignored, unless they specifically function while underneath a LRIG or SIGNI (such as the ability of E - Lectro Bike, Code: Art).
Whenever a SIGNI leaves the field, all of the cards that were underneath it are put into the trash.
Cards attached to SIGNI are not considered to be "underneath" them, even if the attached cards are physically placed underneath the SIGNI they are attached to. The same applies to Traps and Seeds in the same SIGNI Zone.
