Quakebringer does a lot and is not afraid of removal spells!
Each copy of Quakebringer will keep dealing 2 points of damage to your opponent each turn, which means 8 points of damage, if you have all four copies discarded.
Of course, you will need a strong base of Giant creatures to stay on board for this effect to work, which shouldn't be too hard in the Kaldheim meta, where Giants are favored not only in quantity, but also in quality.
Changelings could help a lot in this case, as they fit any tribal deck. So it looks like due to Quakebringer this season's Giants players will have a blast winning many games in the future.
