Molten Tributary costs less than a dollar, whereas Volcanic Island has a TCGPlayer Market Value of $545
Both are sorcery-speed (unfortunately), but still quite strong
Both creatures are extremely synergistic in our deck, with toxic letting them give our opponent a poison counter, but also because they both have abilities that trigger when we proliferate, with Voidwing Hybrid coming back from our graveyard to our hand, making it an infinite blocker and a recursive toxic attacker, and Venser making Golems that help keep us alive while we are executing our control plan

The shock lands will hold value for years to come, as long as people are playing competitive Magic, and the serialized cards are always valuable, especially if you get one of those cool numbers like 069/500 or 420/500 (if you pull one of these, please let me know)
I still have to pay the casting cost, but a tutor effect with no mana restriction has to be good
