Rush decks don't do that great against an RoL/Hope either once the Hope gets rolling.
RoL/Hope is counterable by AoE CC like Rain of Fire and Thunderstorm. Does this card have counters?
Since this card relies on quantum, you could use PC or denial.
Packing Quicksands or Explosions in a deck doesn't cost that much.
If you want to deal with PC you could also run Protect Artifact, which then strengthens the
/
synergy.
It does great against some decks and not so great against others like Hope, and has a potential weakness.
I think Oldtrees opinion is needed on this.
