I don't remember seeing this...anyways here we have Scyther from Jungle, another good ol' Blast from the Past, and most notably (I believe) introducing an attack that boosts another upon use. Statwise 70 HP was and still is pretty good for a Basic, :fire: Weakness was eh considering Charizard (every fanboy's deck) was lying about, -30 Resistance to :fighting: was amazing (given the dominance of haymaker decks using :fighting: Pokemon, Scyther was both at the same time a great card for haymaker decks and a great counter to them), and no Retreat Cost allowed him to flutter about with ease. Swords Dance of course is his main selling point; :grass: to boost Slash up to 60 damage comboed perfectly with DCE, and was about as close to a 1-2 punch as you can get. Granted, Slash itself was only mediocre (at the time) at :colorless::colorless::colorless: for 30, but getting the initial Swords Dance in, them spamming it often ensured success. And did I mention that great Resistance to :fighting:?
In comparison, we have a more modern day example with Zangoose from CL, about as close to a copy as you can get, with just a bit more HP, differing Weakness, more expensive Retreat Cost, and his attack lets you throw a random card from your opponent's hand into the Lost Zone; granted, the Lost Zone mechanic itself has largely been proven fail, but it's still...something?
Unlimited - 1/10 (Not much use anymore, he's just a grandpa now relating glory stories of likely many duels with Hitmonchans and the Machop/Choke/Champ line)
