If you don't want to grind for Controlled Blink, then regular Blink is your best bet. Rapid Deconstruction and Shatter can get you in, too, but odds are the grind will be even worse than Controlled Blink. You're probably looking at about a one-in-six chance that you'll get dropped on the Zot trap before getting dropped on the other side, so make sure you have to take the minimum possible number of trips. On the plus side, on the way back up with the Rune teleport control will work normally.
You can also teleport roulette to get past it, but be prepared to face three or so greater mummies at once if you get a bad result.
Zot traps do, indeed, have infinite charges.
