While playing the "Chaos Reigns" deck, anything is possible! Although your deck is mainly blue, red, and green, it contains spells of all five colors. Early in the game, it's important to develop your mana base by searching up new lands. Late in the game, you'll overwhelm your opponents with flying creatures. But in the middle is where all the fun is!

Your deck is centered around the cascade ability. Every time you cast a spell with cascade, you can get a random free spell off the top of your library. The bonus card could be a five-color creature, a devastating instant, or even another spell with cascade, among other options. But your chaotic tendencies don't end there! Primal Plasma can take one of three different forms. Noggle Ransacker jostles everyone's hand. Rivals' Duel can cause two creatures to fight one another. And who knows what you'll get from Last Stand? As a true agent of chaos, you'll teach everyone else to expect the unexpected.

Some of the cards in your planar deck support your five-color aspirations. Truga Jungle lets lands produce any color of mana, while Windriddle Palaces lets players play cards from other players' libraries: a situation you're uniquely adept at, since you love all lands and can cast anything. Other cards in your planar deck tilt the game on its ear even more than your deck does! Orzhova resurrects all the dead, Hedron Fields of Agadeem causes the Eldrazi to invade, and Time Distortion—believe it or not—makes the game run backwards.
