Just as in the current Congress, the House will pass a ton of bills that, when they get to the Senate, McConnell will strangle in their cribs. Any stupid House bill that inexplicably gets through the Senate will be vetoed by PDJT. Gridlock, executive orders, conservative judges by the ton. RBG stays on life support for another 2 years.
Oh, and since the Senate will not have anything legislative to do, with the House only producing insane nonsense, it can spend all its time getting to the bottom of the FBI/DOJ scandals especially with Lindsey Graham in the judiciary chairmanship - so that should be entertaining!
