The attack Scout lists no damage number. The cost is Colorless. Look at your opponent's hand. Tackle is another attack lists 20 damage. The cost is Colorless, Colorless. Weakness is Fighting ×2. Resistance is Psychic -30. Retreat cost is 1. The flavor text reads "It stands on its tail so it can see a long way. If it spots an enemy, it cries loudly to warn its kind."
I keep a set binder for Neo Discovery, meant to hold every card of that set. This card is one slot in the Neo Discovery set binder. A generation binder holds one card of each species. Sentret can fill a slot in Generation 2 binder (Johto). I still need this card.
