Its paws conceal sharp claws. If attacked, it suddenly extends the claws and startles its enemy.
Prior to the introduction of the Modified format, this card ran rampant in decks mainly because of the ability to do an average of 80 damage and a maximum of 140 damage per turn as early as the second turn provided a deck's setup went smoothly, combined with its zero Retreat Cost and no Weakness. In comparison, the next strongest 2-Energy attack available with minimal drawbacks was Base Set Electabuzz, which dealt 30 damage or 40 on a coin flip. When the first Modified format (Team Rocket on) came into play in 2001, this Sneasel was specifically singled out and banned from the format. Later joined by Slowking, it would remain banned from the Modified format until the Neo Genesis set was rotated out of the format in the second rotation.
UndauntedSneasel is very similar to this card, with an added Weakness and its Resistance changed from -30 to -20 being the only differences.
