Honestly, I like the system
When you're on the TCGplayer website, you'll want to search for the card you want
If we already have a OP05-110-holly and you end up not finding one, you can still play the OP05-110-holly in your hand
The game expects you to ramp into this attack with cards like the Baby Pokmon (whose attack attaches Energy to your bench for free) and Ho-oh ex (whose attack generates exactly the three Energy types needed by Lugia), since the game's random Energy generation means that just being able to use it once without these effects is a pipe dream at best, and only getting it off a single time probably won't even win the game
That's what I've paid for mine in the past. And then you have the really weird stuff that some collectors will be willing to pay for including things that really don't look like a Magic card at all, save for the stamp by the bottom
If you want to frustrate your opponent by denying their best moves and slowly winning the game, this is the deck to purchase first
