I made this team when I was trying to find a way to include Belly Drum Charizard in a primarily defensive build, and landed on paralysis spam as the perfect partner to let Zard do its thing. Against an opponent whose team is more defensively oriented, as is often the case in GSC, paralysis spam can be incredibly potent, and BellyZard itself needs almost no introduction. With the ability to OHKO the overwhelming majority of the metagame from 75% HP or more, and a fantastic base 100 Speed outrunning all but a few key threats, Charizard can be lethal if provided the proper support. In this case, I dedicated every role on the team to supporting via para spam. Paralysis often forces Pokemon to Rest, and when the opponent is trying to burn off sleep turns, it's the perfect time to set up Charizard. Additionally, a handful of Pokemon such as Raikou, Gengar, and Starmie threaten to outspeed and KO Zard after it Drums, so I need their speed reduced via para to have a shot at sweeping. Zapdos is an excellent Pokemon all around and fills many niches, there's almost never a reason to exclude one of it and Raikou from any GSC OU team. Starmie usually runs Surf and Psychic in addition to Spin and Recover, but on this team I decided the ability to paralyze Snorlax and Electrics on the switch-in was more important than extra damage on Cloy, Champ, and Gar. Umbreon serves as one of the CurseLax checks, helps me trap Ghosts for my MonoLax, and spreads para with Zap Cannon. Rhydon's set is particularly unique, as not only am I using Zap Cannon for para, I'm also using Counter over Rock Slide, which lets me nab the clean OHKO on an opposing Zapdos using HP Ice. This is extremely relevant since Zapdos speed ties with Charizard and is hard to keep status'd due to its RestTalk spammability. I went with a Lovely Kiss Lax to give my team some disabling potential beyond paralysis if there was something particularly scary I faced, not to mention it's great catching enemy Cloyster and Snorlax off guard. Body Slam over the far stronger Double-Edge is yet another capitulation to the power of paralysis. Finally, we have Charizard in all its glory, who will make an appearance as soon as the conditions for its sweep are met. Ideally, by the time the opponent realizes you have Zard in the back, there's nothing he can do to stop you.
This team is not without its weaknesses. It's better against defensive teams that use Rest more and attack less often. Against offensive teams, sine it's fairly predictable in its defensive options, it can get picked apart by well-timed Explosions from the opponent. It doesn't have any Toxic immunity, and status can be crippling for both Umbreon and Rhydon, so Zapdos and Snorlax usually have to take status in their place. Speaking of Zapdos, it's the lynchpin for checking a variety of threats, and if it dies somehow, things like Vaporeon and Machamp can be devastating. The team as a whole isn't particularly reliable. 5 out of 6 Pokemon are using less than 100% accruate moves, and every slot is focused on the single goal of setting up Charizard and sweeping with it. If Zard is accidently phazed out too early and revealed, or if it's never met its sweep conditions, it can be complete dead weight, and the only other options to close the game out offensively are a Curse LK Lax and good old Zapdos. However, in an even or favorable matchup, and with a little help from full paras and some of the more unique tech choices, this team can be impossible to overcome. It needs to be played with great caution, and it's as much about the mindgame of Charizard's presence and your opponent's temporary lack of knowledge surrounding that fact as it is about the gameplay itself, but I firmly believe that with proper execution, it's one of the best "anti-stall" teams I've ever seen, and certainly the best one I've built myself.
