If a "Kashtira" Xyz Monster is on the field and a player controls 2 or more monsters: They must banish monsters they control, face-down, so they only control 1 monster.

If this card is banished: You can target 1 "Kashtira" Xyz Monster you control; add 1 of your "Kashtira" monsters attached to it to your hand, then you can Special Summon that monster from your hand.
