artifice, time streams, stroke of genius

Nifty. Looks pretty cool. I don't see anything here that makes it need to be 5 mana though; at 4 mana it's just Turnabout or Concentrate, so I think take it down to 4.

Is it problematic that this is a three turn clock?

"Ultimate" will be explicitly spelled out before the ability. Not all PWs will have Ultimates.

oooh, repurposing unofficial terminology to mean something slightly different is going to be an extremely uphill battle. And also turns it from a plausible (although horribly non-interactive) mechanic into a parasitic one.

Yep. In that case I suggest re-using the word climax from Scenes. Though on second thought that would mean that your reply would instead be "Urza can't climax." and maybe you don't want to go there.

Ultimate and Climax give different amount of points.

How is naming an existing mechanic suddenly turn it into non interactive and parasitic?

Well, you already specified the card type with each of them, so just change the description I quoted above thusly:

> "You get Victory points by activating a planeswalker's Climax (3 pts.) or scene's Climax (2 pts.). Need (7) VP to win."

I mean, we can also open a whole discussion about the reasons behind those numbers being different. It basically says "Activate climax abilities three times to win, except if all three are from scenes you need one more activation."

I vaguely understand scenes have only two activated abilities and their ultimate ability always seems to be a climax ability, so there is a slight understanding that there is a more inherent tendency to activate them, but otherwise scenes and planeswalkers (with designated ultimate/climax) are not that dissimilar.
