Fruity Pebbles and Cocoa Pebbles are both multicolored combo decks, the only key difference been Cocoa Pebbles using Necropotence while Fruity Pebbles used to rely on blue card-searching and countermagic. The deck would win by putting together a Goblin Bombardment and Enduring Renewal with a creature costing 
such as Shield Sphere and Phyrexian Walker. The creature would be sacrificed to the Bombardment, Renewal would it return to hand where it would be cast again, repeating this until the opponent would drop dead.
