Squirrel Sanctuary

The clever part is not the Squirrel it makes on the way in: it's the way this enchantment refuses to stay spent. Sacrifice-based decks live and die on their fodder supply, and the usual constraint is that a permanent used to generate value stays used. Here, every nontoken creature that dies offers a bounce back to hand for a single generic mana, meaning the same green enchantment can be replayed for another Squirrel over and over, one death at a time. That turns a one-mana permanent into a slow, self-refilling token faucet: feed it a death trigger, pay one, recast it, bank another body. The design lets you throttle the loop rather than trigger it automatically, so you decide when the return is worth the mana and when the enchantment is better left on the battlefield as a source of future value. Note the asymmetry that keeps it in check: only nontoken creatures dying arm the return, so the Squirrels it produces cannot recur it themselves, and the loop always costs you a real creature plus mana to reset. It slots naturally alongside sacrifice outlets and death-payoff engines, where the mana you sink into bouncing it is repaid in tokens, drain, or graveyard fuel. As a standalone card it is a modest body-maker; wired into a machine that wants bodies to die, it becomes a recurring investment that never fully leaves your hand.
