How it works

Erosion gives +4 Mult for every card your full deck is below its starting size. A standard deck starts at 52 cards, so destroying 10 cards means +40 Mult. Some decks start smaller, such as the Abandoned Deck at 40 cards, and the baseline follows that. Adding cards lowers the bonus. It is Uncommon, costs $6, available from the start, and Blueprint and Brainstorm can copy it.
