Version 2 of this design is increases tray size slightly to possibly accommodate sleaved cards, while still allowing for the box layout as pictured
When one or more cards are milled this way, exile target enchantment, instant, or sorcery card with equal or lesser mana value than that spell from an opponent's graveyard
Popular sizes include: Approximately 1.5" 2.5." These cards are like inserts or special editions
In fact, if you want to get hold of Shivan Dragon in order to use it in your deck, rather than as a collectors piece or investment, you can pick it up in any number of reprint versions for a few pennies
Later in the game you should be able to pay the escape cost, especially if you have any amount of self-mill (dredge, Im looking at you)
Twin Long Rods #1 is certainly not getting a spot in my deck, thats for sure
