So, I'm pretty sure everybody already knows that now all PW are legendary, so they follow the legend rule, i.e. you can have as many Jace you want in play, if they don't share the same name.
I know that there was already some lore problem with havin multiple cards of the same character (like the two Thalia), but I think that this was explained that you aren't really summoning Thalia, but her "image", so you can summon here from different timelines.
How this can work with PW? You aren't summoning them, you're calling them for help... How can you call for TWO Jace at the same time? I know lore is second (or third or fourth) to game mechanics, but still...
Couldn't the explanation just change to reflect the Thalia example? You aren't really summoning Jace, you're just summoning the 'image' of Jace so you can summon him from two different points in his timeline. Loyalty is just a reflection of your perception of his attitude toward or tolerance of you at the time, while the abilities he can use are those you saw him utilize at that particular time. This would also explain why the same planeswalker that just noped out of a given situation would be perfectly willing to help you again two seconds later, why planeswalkers who absolutely despise each other are suddenly willing to work together if you happen to call on them, and why we can still phone up planeswalkers in states they are no longer in (i.e. I could still play Sarkhan the Mad despite him no longer being mad)
That, or you could be calling up a given planeswalker and magically inducing a particular mind and skillset of their's you remember, with multiple personalities playing the role of additional versions of them each with their own perception of ongoing events (and thus potentially different loyalty points despite being the same physical being) and personalities becoming inactive when they attempt to planeswalk away.
I think that PW aren't summoned however, because a PW cannot summon another. I can understand what you mean, however, especially for the "old self" of the PW.
So I never liked the introduction of Planeswalkers as cards because they sort of flew in the face storyline. But when I stopped thinking of the cards as actual walkers on the field and as "pacts" it felt much better. You as a Planeswalker have made an agreement with another Planeswalker, willing or unwilling, in exchange for mana, the loyalty count can be seen as how binding your "pact" is, damaging a Planeswalker is more like interfering with your alliance or scheme.
As such it might make sense that a walker could be running multiple deals but can't have the exact deal going on twice.

I like the former. It's less convoluted.
Test of Metal is canon after all.

Ah ah ah, excellent!
