Yeah, the Intercessor is perfect for that. The only dupe is the card you plant in your location, which can be days before your performance. I think the Intercessor is stronger than Angle Zero, because it's the whole card (minus a corner) that vanishes and reappears, not just a corner.
One cool thing you could do is ask the restaurant if you can come in before it opens on a night you're working, and plant a few cards different places. Then experiment with the tables.
The beauty of the Intercessor is that the spectator can tear off part of the corner, and hold onto is without you ever touching it. Unknown to them, It perfectly matches a card you've torn days ago. Genious.
Trust me, you'll have so much fun with it, playing with different ideas and locations and such. There's even a full fledged stage routine involving fruit in the booklet, using the intercessor
