If you're in a politics deck, it's a great tool
Hurl Through Hell Look, I probably shouldve just talked about how cool the Prosper, Tome-Bound deck is instead of making this list, considering so many of the cards in here are from that deck
They can even merit the ability to run a Synchro engine using Junk Synchron and the like
You could drop your opponents hand (lets say he/she took a prize last turn and has a decent-sized hand, likely to have what they needs for next turn) to only 4 cards by using N, but that leaves yourself with only 4 cards-worth of refresh
That small difference in sleeve size helps protect edges, improves durability, and keeps your deck shuffle-ready
Make sure you pack in some sacrifice outlets for quick access to your cached cards and to prevent your opponents from exiling Toluz, making the stored cards moot
