These are the best Madrigal decks, not the best Amber/Amethyst decks
Trade Secrets This is an unusual one: it's a collusion card, meaning two players can collude to each draw tons of cards
Ragavan is an absolutely brilliant creature, and he is worth using in Commander in addition to Modern
The tribe's massive diversity does a ton, from destroying a variety of things (Wispmare, Deepfire Elemental, Fulminator Mage, Ingot Chewer, Hateflayer, Tornado Elemental, Cinder Elemental, and don't forget Shriekmaw) to having severely powerful beaters (Verdant Force, Multani, Maro-Sorcerer, Silvos, Rogue Elemental, Liege of the Tangle, Lord of Extinction, Avenger of Zendikar, Thornling, and Root Elemental) to some of the best utility creatures you can imagine (Reveillark, Brine Elemental, Vengevine, Fertilid, Smokebraider, Forgotten Ancient, Stigma Lasher, and Briarhorn) and finally to great control creatures (Dread, Windreaver, Dawn Elemental, Air Servant, Ashen Firebeast, Roil Elemental, and Time Elemental)

Ganax makes a [cad]Treasure[/card] token whenever it or another dragon enters the battlefield
