The deck floods the board with Pests, Bats, Insects, Snakes, and Spiders, then repeatedly gains life to trigger Blech and stack +1/+1 counters across the entire creature base. Life gain is generated through a variety of sources — creatures, enchantments, and spells — each trigger pumping the whole team simultaneously for explosive power growth. The win condition is creature combat, leveraging a wide board of continuously growing creatures that scale faster than opponents can handle.
