高い攻撃力を誇る伝説のドラゴン。 どんな相手でも粉砕する、その破壊力は計り知れない。

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.)
