The Rock Wrecker attack for the Community Day with Rhyhorn in February has been added to the game files of Pokémon GO. Therefore, we now know how strong this attack is.
This is Rock Wrecker: The attack has already been announced for the Community Day voting. Until now, it was not known how strong the attack is and whether Rhyperior would actually be good with it.
Now the values of the attack have been added, and one can get an idea of whether Rock Wrecker is actually a good attack.
How strong will Rhyperior be with Rock Wrecker
These are the values: The damage per second is powerful and catapults Rhyperior to the second place among Rock attackers.

However, it should be noted that it is significantly more durable in battle than a Rampardos. So, anyone looking to save potions will find in Rhyperior the best option.
With its Catapult and Rock Wrecker, it is even better than Tyranitar and Terrakion and is considered one of the best counters against Voltolos, one of the next raid bosses.
Should one secure the attack? Even if one does not play on Community Day itself, one should at least secure the attack and evolve a Rhydon into Rhyperior.
It is best to evolve several specimens right away, as Rhyperior will also remain one of the best Rock attackers in the future.
How can one obtain Rock Wrecker? This attack will be available on Saturday, February 22, from 11 AM to 4 PM by evolving a Rhydon into Rhyperior.
Rock Wrecker will not be available through TMs or after this event.
What else is there at the Community Day? In addition to the strong attack, there are also other bonuses at the event. There will be triple Stardust for catching Pokémon and three-hour Lures.
The highlight is the introduction of Shiny Rhyhorn and the increased chance for the shiny variant.
Lastly, there has been a lot of criticism regarding the egg events in Pokémon GO:
