Yes, sometimes things go to far and we get something like Ironworks, and sure people love to complain about Tron, but Ancient Stirrings is usually just propping up cards that would never see play otherwise like Hardened Scales and Codex Shredder which is great
I would describe Temporal Spring as a tempo based disruption effect primarily used to slow your opponent down
All cards that arent on the battlefield, spells, and permanents are the chosen color in addition to their other colors
Creatures you control gain lifelink, indestructible, and protection from each color until end of turn
It has convoke and delve, which means that the cost needs to be paid by at least two green/black creatures and five cards from your graveyard
You dont want to rely on luck to pull you out of a sticky situation
