Gold Star Espeon and Umbreon ($5,000 and $6,000) These cards are scarce and one in a million
A spell that's put into its owner's library doesn't resolve, but it isn't countered
If a card feels off in your hand compared to others from the same set, trust that instinct and investigate further
Shrapnel Slinger - 9.84 Not sure what folks have against this card, because it seems like a perfectly fine two drop to me, with some added upside if your opponent happens to have an artifact that just needs to die
Canopy Lands Kickstarted by Horizon Canopy in Future Sight well before more canopy lands/horizon lands appeared, these are solid cards you dont want too many of
Fetchlands like Misty Rainforest are great ways to reset the top of your library to get a fresh look with The Fourth Doctor, but Id also recommend trying out cards like Bant Panorama and Shire Terrace which enter the battlefield untapped and tap for colorless mana in the early-game, and then you can cash in for a basic land and shuffle your library later when you need it
