Linked Ground

[Link 85]

Normal Spell Card

Pay 500LP, then choose 1 of your Monster Zones; it becomes a Linked Monster Zone for the rest of the Duel.

I don't know how Link Monsters work too well, so I may not be the most eligible judge, but this card seems way too powerful.

 

Its relatively low activation cost and the fact that it can be activated on your first turn, before your opponent can react to it, make this card extremely broken.

 

I'd make the card a continuous spell with an activation cost of 1000 and remove the 'for the rest of the Duel' clause. That way, the opponent can still react to the activation of this card, and having to activate the card multiple times per Duel has a significant impact.

Normally, to have a Linked Zone, you need to have a Link Monster whose Link Number and Link Markers are pointing toward a Monster Zone, changing it into a Linked Zone. I suggest you change this Spell so that it can only be activated while you control a Link Monster and its effect lasts only while that Link Monster is on the field. That way, it's not so overpowered and fits somewhat better with the metagame.
