It seems as though only a third of the deck's creatures are squirrels but it has plenty of cards like Chitterspitter that'll help you create a formidable army of vicious rodents
Some sets faced more competition than others, especially Generation Four, which included Diamond, Pearl, and Platinum alongside HeartGold and SoulSilver
You also have access to Howling Mine in the retro-frame reprints, which will guarantee you get a second draw every turn, no further work needed
This is a long winded way of saying that even though this has an awkward early condition to reach Shock/Forked Bolt power levels you don't ultimately forgo that power, you just save it and as such are generally able to use it more effectively
Then, if you're a collector or you're ok with spending way more money for the same exact card, you can spend way more money on it
