Smashing Ground is one of the best spell cards that we currently have. Once we lost Raigeki and Dark Hole this thing was the next best thing. Of course we had Fissure, but this thing is way better.
If an opponent plays Fissure you could alwayZ chain Scapegoat and just lose a token. In Card Exchange it's a 1-1, but you just missed your target and gave your opponent another zone to bring a monster out. This is why people choose Smashing over it.
There isn't to much need to review this card because in the average deck you'll see any where between 1-3 copies. This means you need to be ready to play against 2. It's a quick 1-1 that can be avoided with a well play Book Of Moon. Just play your cards good and this thing is great.
Traditional: 2.5 (Riageki and Dark Hole are here)
