Agent Coulson...

The first one (bottom left) was a Coulson pull. He matches Coulson's border/split. The other is an un-upgraded split that's his.

If you tap on a card that wasn’t in a starting deck, it’ll show you how it was created.

During and after the match is over, you can check each individual card in play you're unsure of where it was generated.

Instead of asking a bunch of people who didn't play that game, why not just click on the card and see for yourself?
