It's not like they ran out of cards: there's Mycosynth Gardens and Encroaching Mycosynth
However, if you get one down early and have expendable creatures, it might be worth trying
While most decks look to cast the Sorcery for one or two mana, removing almost any early game permanent, some decks even splash a fourth or fifth color to unlock the full potential of Prismatic Ending
Ifrit GREEN: Summon: Fat Chocobo, Chocobo Kick, Town Greeter, Balamb T-Rexaur, Goobbue Gardener OTHER: Adventurers Airship, World Map, Crossroads Village, any two-color Town Toms fate was sealed in 7th grade when his friend lent him a pile of commons to play Magic
This will do a lot of work in decks that can churn out tokens (again, like Kykar), but its still a card with a lot of potential upside in the right build
That way, youll always have something to cast and take less damage on each step
