So I was having a look at the new moves; and saw the Signiture moves of the fossils; Bolt Beak [-Zolts] and Fishious Rend [-Vish].
These attacks are 80 BP; and 100% Accurate Electric and Water moves... but their power doubles if the user goes first.
Draco- fossils have Base 75 Speed; enough to outrun most defensive pokemon. Arcto-fossils have 55 Speed. It's also worth noting that the -Vish have 90 Atk and the -Zolts have 100.
55 Speed is certainly low enough to be reliable in a Trick Room setting. However, Draco-Fossils get Sand Rush; and Arcto-Fossils get Slush Rush.
While the Arcto Base 55 Speed isn't as impressive, Base 75 on the Draco Fossils is enough to probobly outrun most pokemon in it's respective weather.
So Draco- Fossils could happily be running around smashing things with 160 BP STAB's in Sand.
That's... pretty scary. Especially since you could slap on a Choice Band. Maybe Base 75 is just enough to be a passable scarfer. I've not seen speed tiers in the Galar Dex yet. Bonus points for a Scarf Zolt set potentially taking advantage of Electric Terrain set up by an ally. As hinted before; Band Zolt can outrun walls and might just be able to brute-force through them.
I think DracoZolt is the most scary. Dragon-Electric is in general a good typing, but it has 100 Base Atk; 75 Speed and Sand Rush, while slamming things with a potential 160 BP STAB.
Also wow the empowered formes of the Legendaries have 720 BST AND get a free +1. They... might be too Uber, although they do have to use their item slot.
Also the ever-adorable Snom has the 3rd lowest BST on record; hardly beating Solo Wishiwashi and Sunkern. And Snom has a smaller movepool than both. It's weaker than Baby Pokemon.
Clearly; this means we must all protec Snom.
