In chaotic your decks consist of: 1,3, or 6 creatures; 1,3,or 6 battlegear(weapons used by the creatures; 20 attacks; like 10 locations; and 1,3,or 6 mugic cards. I think it is more skilled because you aren't just playing creatures and using the attack points. Intead, all of your creatures are already on the field and you must play attacks to damage other creatures.
