* Since this card is always treated as an "[[Elemental HERO]]" card, you can [[Fusion Summon]] this card by using with "[[Miracle Fusion]]" or "[[Parallel World Fusion]]". Alternatively, you can also Special Summon this card with "[[Armed Neos]]", "[[Elemental HERO Grandmerge]]" or "[[Favorite Contact]]".
* This card goes well with "[[Safe Zone]]". The longer "Chaos" stays on the field the more opportunities you get to benefit from its effect and "Safe Zone" makes "Chaos" invulnerable. In addition, "Chaos" can use its effect to stop any card effect that would [[destroy]] "Safe Zone" (e.g. "[[Mystical Space Typhoon]]", "[[Lyla, Lightsworn Sorceress]]", "[[Evolsaur Diplo]]"). Also, if your opponent has no more monsters, you can use the effect of "Chaos" to negate "Safe Zone" and attack directly.
