GC holder - What should I do with earlier I94 card

[immiasst]

I have the I94 card that I got at the port of entry a few years back. In meantime my GC got approved. What should I do with the I94 card which is stapled to my passport?

Should I give this back on my next travel?

Please advise.

Keep it as souvenir, or throw it away. With the GC, it has become completely irrelevant.
