They could Link Summon a monster, use its effect, Link Summon something to a new Zone it points to, Link Summon something there, use that thing's effect, Link Summon something using the first Link Monster as material to a Zone the 2nd monster points to, and use its effect thst would only work if it were in that specific Zone. They could call it Hyper Link ; ) Summoning or something like that.
Please note I've not actually watched VRAINS yet so if something like this has happened, ignore me.
A Link monster whose effect only works in certain zone(s) does not exist yet, but Yusaku, Revolver, and Spectre have perfomed "Link Climbing", spamming Link monsters which are then used as materials to summon a bigger Link monster.
And both Revolver and Yusaku have performed Extra Link, although Revolver is the one who made the true Extra Link, Yusaku just took advantage of Revolver's Link monsters in both EMZ having a Top arrow (Congrats Revolver, you've just played yourself) to create his own Extra Link.
I think it was a misplay on Bit and Byt-sorry wrong series, on Bit and Boot's part. But I've got a feeling something familiar might happen. Remember back in the first duel when that Knight of Hanoi played Cracking Dragon in front of the Extra Monster Zone that Yusaku eventually used for Decode Talker and we all know how that turned out, some episodes later Varis uses Cracking Dragon and uses common sense by putting it in the middle zone. So maybe when we get to the first boss villain in season 2 they might be like "I'm playing this in the middle because my minions are idiots" and give our heroes a hard time
Emma actually did a similar misplay before in her Speed Duel against Yusaku - placing her Link, which has a Bottom and Bottom Left arrows, on the Right side EMZ instead of Left side EMZ.
The Left side EMZ was empty at that time, so she could have chosen the Left one, which would have made both of her Link's arrows usable.
The unusable Bottom Left arrow ends up being irrelevant to the remainder of the Duel, but making both usable still would have been a better play.
