"Red-Eyes" based Decks typically focus on getting it into one of its many alternate forms, as on its own it is rather weak for a monster of its Level. Compared to its rival, the "Blue-Eyes White Dragon", it is very easy to upgrade and several Dragon-based Decks work well with this archetype of cards.
This new support is purely offensive in nature, incorporating massive Burn potential. For example: both "Black Skull Archfiend Dragon" and "Black Flare Dragon" if the conditions are met, can easily deal a minimum of 2400 damage after a single attack and without counting any battle damage possibly done. The new Xyz Monster, "Red-Eyes Flare Metal Dragon", can burn the opponent by 500 points each time they play a card, which can accumulate rapidly for massive damage. Even without much protection to themselves, this adds massive swarm ability to "Red-Eyes" Decks. "Red-Eyes Darkness Metal Dragon" can Special Summon "Red-Eyes B. Dragon", supporting other cards like "Red-Eyes Spirit" and "Return of Red-Eyes" thus being able to easily overwhelm the opponent through sheer power. Also, the new "Black Metal Dragon" can be equipped to "Red-Eyes" to enable it to rival "Blue-Eyes" in terms of raw ATK power, and (once it is sent from the field to the Graveyard through any means) can add a new "Red-Eyes" card from the Deck to the hand, such as "Red-Eyes Fusion" or "Darkness Metal Dragon".
