DANE-JP020 妖醒龍ラルバウール Youseiryuu Larvalaur / Larfae Dragon Larvaur
Level 1 DARK Dragon Effect Monster
You can only use the 1st and 2nd effects of this card’s name once per turn, each.
(1) If a monster you control is destroyed by battle or an opponent’s card effect: You can Special Summon this card from the GY (if this card was there when that monster was destroyed) or hand (even if not), and if you do, banish this card when it leaves the field.
(2) If this card is Special Summoned: You can target 1 face-up monster on the field; discard 1 card, and if you do, add to your hand 1 monster from your Deck with that target’s Type and Attribute, but a different name.
Considering this card is of the same ‘theme’ as Levianeer and Tiamaton, it’s likely this card’s name is based on most likely the words “Larva” and “Balaur”. Balaur is a Romanian Dragon from folklore, often many-headed, fish-like and quite wicked.
The other part of its name, Youseiryuu is probably referencing both Yousei (Fairy) and Yousei (Larva). As in like a Dragon Whelp or something.
