Venusaur was the final evolution of Bulbasaur, the Grass-type starter that roughly a third of all Pokemon players chose for their first journey, and that emotional connection has kept Venusaur cards trading at premiums that reflect its starter status even though it has never quite matched the market dominance of Charizard or the cult following of Blastoise
Many archetypes have a card that will let them draw through their deck, such as "Sky Striker Mobilize - Engage!", "Folgo, Justice Fur Hire", and "Runick Fountain", but have some sort of archetype restriction on it requiring the player to jump through hoops or set up a condition for it to offer maximum benefit
