With a decent statline and middling cost, the field mice already make for a pretty good card even ignoring the sigil. Fecundity lets you play essentially limitless mice, so long as you have enough copies in your deck. This means you can use them to clear out a lot of your deck, leaving less up to chance, or just get out a small rodent army. Keep in mind that you can also sacrifice the mice to other copies of the card, so you can sort of act like you're moving or healing your mice for the cost of a single squirrel.
