OK Charzard (as you may or may not know) is not just for the early day fanboys of the anime and TCG, in honesty I never felt it was that great in gen 1 either; in gen 2 however it became a dangerous brute. Gaining Belly Drum and Rock Slide it was able to cover Earthquake in the physical side as well as becoming the fastest Belly Drummer in the game. Its speed tie with Zapdos plus the fact it can administer big hits with Fire Blast, without the need for a setup can make it tricky Pokemon to counter once it's in play. The reason it isn't that popular is because it is a hard pokemon to bring into play; it doesn't really synergize that well with anything and doesn't have good defensive characteristics itself. The payoff is high with this guy tho, he's great at putting opponents in check mate if you patiently wait for the right moment to use it.

Essentially you use Raikou and Kingdra to spread paralysis (don't get cocky taking on electrics with Kingdra). This team didn't pop out the box as being super useable, it's a little weak to Snorlax because it leans on Forretress so much to check it, once I learned you have to dance around a little fishing for that Fire Blast it actually worked quite well. If I remember rightly a fully cursed Forretress doesn't OHKO a fully cursed Lax with Explosion? So Toxic just feels right there, obviously unless it's a fire lax you should be able to take all of them with this Forretress. Rhydon because he's awesome offensively and defensively, he really helps checks Snorlax, kills Skarmorys if Lax sleeps them and can sweep and devastate with paralysis spread. Kingdra speed ties with Nidoking and doesn't have the electic weakness, but still can't really stay in against electrics. Dragonbreath is pretty cool, I usually just session it and use the para to set up for Rhydon or Charizard. Charizard really you try to save to the end (unless you see an oppertunity to check mate, or have to play it). To sweep with 'zard you need to have their electrics paralysed, damage doesn't matter, about 80% health on their water types (depending on the poke) and Machamp, paralysis doesn't matter unless it's Starmie, 70% health on Lax?? I think?. Miltank can be a problem as it speed ties, it's better to try and paralyse it. Eggy can survive F.Blast with a low roll but not by much, spikes are great. Umbreon can be a problem for this team, sometimes Rhydon can suck a Toxic being the only phazer and that really screws him. Sometimes Umbreon can be the window to Belly Drum with Charizrd though as it isn't immediately offensive.
