For context on just how under the radar Brainstorm was, heres the eventual champion and shortlist Hall of Fame candidate, Justin Garys U/R list from that same event: Creatures (12) Lands (22) Spells (26) 2 Nevinyrral's Disk 4 Counterspell 4 Dissipate 4 Force of Will 3 Earthquake 3 Disintegrate 2 Incinerate 2 Serrated Arrows 2 Binding Grasp Sideboard Super rad deck, to be sure, but definitely could have benefited from a playset of Brainstorms
Note that there is no "nontoken" word here, so instant speed artifact tokens will trigger too as well as lands that make them like Mirrex
Each Collector Booster contains the following: 4 Traditional foil commons 3 Traditional foil uncommons 1 Traditional foil full-art impossible basic landone each of the five basic land types 1 Non-foil showcase magnified or showcase dossier common or uncommon A Booster Fun uncommon (20 uncommons total) appears 37.7% of the time with the remaining 62.3% of the time being a common (11 commons total)
The key thing with Ureni is unlike Craterhoof, it prevents the crack back if you are unable to finish them off that turn
This isnt the case for a majority of singles in MTG Final Fantasy, but these are certainly the exceptions
