Most of those, however, aren't worth a thing
If timed right, it can be used on turns you arent ready to attack anyway, and could be worth a try
A card bearing a first edition mark on the side means its from the first print run of a card set, which gives it extra value
It protects the monsters it points to from battle, and its effect calls forth Goukis from your Graveyard for instant tag team action
Please note that XLHQ versions of cards are only showed in the zoom view, regular card pictures are still used (LQ/HQ, depending on what you're using) on the battlefield and elsewhere in the game because XLHQ art is significantly more taxing in memory consumption (and in addition to that, XLHQ card borders are not cropped the way Forge expects them in order to show them properly on the battlefield anyway)
They range from weapons to magical devices, offering diversity to the game
