It is not the end of the world to cycle it for one life and one card if you have things you want to dig for and nothing else to spend the mana on and this is pretty much the worst case scenario
Right now, according to TCGplayer, there are four gold-stamped art cards with a market price above $10: Y'shtola, Night's Blessed (Art card #53) $16.05 Nibelheim Aflame (Art card #35) $14.02 Sephiroth, Fabled SOLDIER (Art card #44) $10.47 Tifa, Martial Artist (Art card #52) $10.31 (this uses a stamped planeswalker symbol instead of an artist signature) Beyond those, there are another eight art cards currently above $5 (all of which contain the gold-stamped artist signature)
Rating: 2/5 And that's Emerald for you
Even just getting one Spider out of this will feel great, and it feels like UB is well-equipped with enough ways to make this evasive that it will feel pretty strong when it lines up that way
