We also get to dump +1/+1 counters on each modified creature we control at the end of our turns
FALLOUT COMMANDER: ARTIFACTS & LANDS Ah, the Bobbleheads
Toss in the fact that Thalia, Guardian of Thraben already has several printings including a WMCQ Promo with unique art and I'd guess that the pricing of the different versions of Thalia, Guardian of Thraben will look much like the pricing of the different Secret Lair printings of Serum Visions with the one with the most desirable art being slightly more valuable than the rest, but the total value ending up right in the $30 or $35 range
We often take these top-down cards and give them very on-the-nose names to make sure that people will understand the references without the aid of art
The Secret Boomer History of this card is that back in the day, when casual players were terrible (unlike today, right?), we used to say things like: I am packing Swords for emergencies, and also in case I need to get rid of my Force of Nature or Lord of the Pit! I mean, you could do that, sure, but we were so worried about life we actively sought ways to play Stream of Life in our main deck
