#3: Rats: Cost: $40, Current Value: $79 Considering that Rats joins Cats (and basic lands) as the three Secret Lair drops worth double the cost of their drop, maybe it isn't just cute Cat art that drives prices of Secret Lair cards but cute animal art in general
Your modified creatures have trample, and connecting with combat damage ramps you a land
It came out at around the same time that the Pokemon anime series was airing, guaranteeing its success
And getting a near mint condition of this card isnt going to cost you nearly as much as the other Charizards on this list, but could run you nearly $800
The current Standard format has quite a fantastic array of sets available to make decks with right now (Sword and Shield, Rebel Clash, Darkness Ablaze, Champions Path, Vivid Voltage, Battle Styles, Chilling Reign, Evolving Skies, Fusion Strike)
