Blue-Eyes comes with a very special caveat about its usage.

Level 8 LIGHT Dragon Normal Monster (LEGEND)
(This legendary dragon is a powerful engine of destruction. Virtually invincible, very few have faced this awesome creature and lived to tell the tale.)
Field Spell Cards are confirmed and they work like they do in regular Yu-Gi-Oh! You place it face-up in your Field Zone, its effects are then applied. If you play a new Field Spell, the old one is sent to the GY, you can play any number of Field Spells per turn.
Regarding Legend Cards:
You can only include exactly 1 Legend Card with the Legend Icon in your Deck, in total. No highlandering a Deck full of Legends.
Regarding Deck Out:
If you would Draw a card and there is no card in your Deck to draw at that time, you lose. (Example: If you have 4 or less cards in your Deck Deck, and your hand is 0 cards, you lose because you cannot draw a 5th card.)
