Chaos Reigns (Casual)

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.
