When this card is Normal Summoned: You can add 1 Gagaga' Spell/Trap Card from your Deck to your hand. You can target 1 other 'Gagaga' monster you control; the Levels of both that monster and this card become the combined current Levels of those 2 monsters, until the End Phase. You can only use this effect of 'Gagaga Sister' once per turn.'
