Foxglove can be a source of card advantage, but lets be real: Anyone playing this fox wants to dump big creatures into play for little to no cost
Luckily, if you've fallen in love with this card, you'll be excited to know it's not difficult to find in near-mint (NM) condition, as it frequently sells on TCGplayer, sometimes reaching into the $16 or $18 range, though others have sold for less than $12
That is great in Rakdos with Cabal Coffers and Urborg, Tomb of Yawgmoth or with Gruul's ramp like Cultivate and Rampant Growth and Explosive Vegetation to reliably get to that 8 mana
But those hoping to resell for a high value may be the biggest customers for this meme-filled set, as initial Magic: The Gathering fan reactions have been lukewarm at best
Competitive viability can temporarily boost prices, but once a card rotates out of standard formats or strategies evolve, those prices drop
Changing it to artifact or creature seems fine
