When paired with consistent graveyard recursion cards found in Commander decks built around creatures like Meren of Clan Nel Toth, Spore Frog can allow its controller to essentially prevent damage that would be dealt to them every turn , keeping them alive long enough to enact whatever shenanigans they have in mind
Five mana to answer one creature just isnt very efficient, and the equipment destruction upside is tied to this evaluation as well
(Any amount of damage it deals to a creature is enough to destroy that creature.) As long as enchanted creature is green, it gets +1/+1 and all creatures able to block it do so
So along the way we get to keep choosing a new ring bearer, and eventually our ring bearer is legendary, cant be blocked by creatures with greater power, loots on attack, forces blockers to be sacrificed at end of combat and hits all opponents for 3 if it hits a player
Despite making fun of fairytale rides and adventures, this ride still looks like a great time
