I can't see congress putting up with any president establishing the precedent that he has such absolute power.
They already have, maobama said he didn't have the constitutional authority to do DACA 23 times. Yet he did it and congress didn't do shit.

Comparing executive orders and presidential pardons is like comparing apples to oranges. GOP could have easily taken Obama's DACA order to court but they were divided and didn't want to touch the issue with a 10 foot pole. Compare it to how Democrats were more united and took Trump's far more legal travel ban to court. Eventually it took a group of states giving Trump an ultimatum to end DACA by threatening lawsuit on a certain date which I don't recall.
The States have filed the suit because of activist judges interference, it will be stricken just like DAPA was. Maybe easier, because the DOJ won't defend it.
