Call the Night Swarm

Bat Colony rewards careful cave management and timing. When Bat Colony enters the battlefield you create a squad of 1 1 black Bat tokens with flying equal to the amount of mana produced from a Cave that was used to cast it, so the card scales with how deeply you have prepared your mana base. As an enchantment the body of work here is steady; it does not demand an immediate answer and it buys air superiority against ground heavy decks.

The follow up trigger that places a +1/+1 counter on a creature you control whenever a Cave enters the battlefield under your control makes Bat Colony a quiet engine piece for incremental growth and board resilience. In build choices where you lean into Cavern synergies the card becomes both token generator and a persistent buff source, useful in attrition matchups and in games where you need to convert mana investments into tangible board presence.
