This tier in played in 5th gen
In RBY cup, the only usable Pokemon are the original 151. The tier features many prominent threats, such as Dragonite, Zapdos and Moltres. Upon closer inspection however, you'll notice how the update to 5th gen greatly affected the original 151. Once dedicated to being an anti-sleep lead in gen 1, Ninetales returns as being the only weather starter in RBY cup, backed up by friends such as Venusaur, Charizard and Arcanine. Magneton gained its Steel typing, making it the only Dragon-type resist in the tier, however Dragonite will often come with Earthquake to thwart the magnet Pokemon. Omastar gained Shell Smash, making it a frightening sweeper indeed, able to outspeed and decimate most of the tier. Our favourite bugs, Venomoth and Butterfree both gained Bug Buzz and Sleep Powder, making them both terrific, hard to wall sweepers. However Stealth Rock greatly neuters them.
Speaking of Stealth Rock, hazards are extremely prominent in the tier. There are a total of 16 Stealth Rock users, 2 Spikes users, and 6 Toxic Spike users. However, there is only 1 Ghost-type in the entire tier - Gengar. While there are a total of 8 Rapid Spinners, meaning it's relatively easy to spin, as Gengar is not renowned for its defences. Although Gengar's excellent movepool means it can take on a lot of the spinners one on one, between both Thunderbolt and Giga Drain. Additionally, many of the spinners in RBY are of the Water-type; meaning that their STABs are neutered by Sun.
