you can only pair the soulbound that was already on the battlefield with something that comes into play under your control. Your cant pair a soulbound on the battlefield with something already on the battlefield

[Bonesword]

Yes you can click on galvanic alchemist and read soul bond

[Birdbrain]

"You can pair this creature with an unpaired creature WHEN EITHER enters the battlefield"

Word for word what it says

[Bonesword]

Yes and one did

[Birdbrain]

Yes and one did

but you can't pair the one that's on the battlefield unless its to the creature that entered the battlefield

can he soulbound something on the battlefield to something already on the battlefield when a creature with soulbound enters the battlefield?

[5/9 Turtle]

After extensively reading this game bonesword did have 2 alchemists out

[Birdbrain]

But you can only soulbound when either enters the battlefield. Not when anything enters

can he soulbound something on the battlefield to something already on the battlefield when a creature with soulbound enters the battlefield?

It depends on what he's trying to soulbond to what. Can I get a description of the play in question? Trying to read through this is a bit difficult. If you could describe what happened I can help settle this.
