This deck is designed to turbo 3 Rey-Eyes Flare Metal Dragon and Borreload Savage Dragon in one turn.
If performed successfully, your oponent must get rid of 3 XZY bodies of 2800 ATK that cannot be destroyed by card effects and a single omni-negate, using only 5 cards or less, otherwise, they'll die.
You must send Red-Eyes monsters as quickly as possible to the GY in order to trigger Red-Eyes Flare Metal Dragon's effect and start to summon multiple level 7 monsters to your field. While using Rokket strategy to summon guardragons in order to get those same monsters, and end up summoning Borreload Savage Dragon.
This deck is best suited for going first. Of course, there are two huge absents in this deck: Red-Eyes Dark Dragoon, which isn't in this game, and Red-Eyes Darkness Metal Dragon, which is banned in this game for some reason.
Keep in mind that this deck is only meant to be played in this game, the format, card pool, banlist and playing mindset is very different from that of TCG, even compared to the format closest to this game (March 2020 pre-ETCO).
