MTG Salvation

That's why I asked. It's a neat effect, but setting up for the ultimate seems difficult if not, possibly, not worth the effort.

What was he using to target, out of curiosity?

In a group that plays broken artifact ramp he's solid. He is fragile like all Planeswalkers so I don't know why anyone would build around him specifically. Early game steal rocks and loot can make him worth a card and late game steal something ridiculous
As I alluded, he is meta-dependant: if people have great/ridiculous artifacts go to town.
