Even if kids prefer getting Vs (I would have loved getting EXs in them decks), the loss of Cracked Ice holofoils was a crushing loss to many collectors (myself included), so knowing that the McDonald's holofoil is still going strong after all of these years
Yugioh operates with a single format that is managed by a very complex ban list (cards are outright banned, or you can only play one in a deck, two in a deck-normal maximum being three in a deck)
The chase 1st Edition holos are Dragonite , Gengar , and the legendary birds ( Articuno , Moltres , Zapdos ), with Lapras and Aerodactyl also commanding strong collector demand
By the way, the target of Zombify may be changed to a creture card in your graveyard, then it can be returned to the battlefield
This kind of effect is quite inexpensive now
It's unfair in its ability to slow down other game plans without affecting your own
