You can only activate 1 "Spright Smashers" per turn
Looking at the last ~10 modern sets (Shrouded Fable, Stellar Crown, Surging Sparks, Prismatic Evolutions, Journey Together, Destined Rivals, White Flare, Black Bolt, Mega Brave, Phantasmal Flames), its clear which have stronger fundamentals
Its completely normal for a single turn to be composed of ten different actions that build on each other just to get a single pokemon evolution, for example, which sounds annoying but is satisfying in practice
(This is treated as its secondary effect) Now, who said I needed a monster to decrease my Life Points to boost my game speed
While we don't have a release date yet(only Late 2019 confirmed) for Sword and Shield, it's expected to release during holidays(November/December)
I've got a few extra bits and pieces to deal with organization, bulk, and color coding in my setup as well (more on that below), but if you're starting out as cheap as you can, you only really need the first two items on this list
