Magic: The Gathering introduced the cascade mechanic in the Alara Reborn set from the ancient year of 2009

However, the fact that they're so cheap also means that they will quickly be outvalued by cards that cost more mana
In such drafts, players will quickly identify their archetype and then go on autopilot, picking the best card for that deck out of every pack (which is filled with irrelevant cards)
Play big spells, get big creatures, and unlike some of these commanders, the good cards you add to this deck will stay good even if opponents are bent on removing Rootha
