The ability here is nice, especially if you can cast multiple spells, but triggering it is far from automatic and even when you do sometimes it wont do anything
Urza's stone was the Mightstone, named after examining it would increase the power of things around it
Comparable to Contraptions from Unstable, Attractions are special artifacts that rather than being cast through traditional means, are kept in their own deck, being put directly into play from atop their controller's respective attraction deck when an ability would cause you to "open an attraction." These special artifacts make use of dice, allowing you to roll for their respective effects during your upkeep
This effect can be devastating, especially in a multiplayer game
