It should be noted that cascade casts the spell it finds whereas seek does not

This is a fan-made product and not an official release

GX Tag Force 3 included Synchro Monsters which are from the 5D's era

If there would have been some actual placement cards I would expect around 8-10k+ for those as theres only two of each from the tokyo dome tournament

Also good to note is that this card works beautifully with Maskwood NexusMaskwood Nexus

However, that base price might not include subgrades printed on the label adding subgrades can cost extra (many collectors opt for subgrades because its a signature feature of BGS)
