Lesser dog is a card with decent stats, however its main appeal comes in the fact it lowers the cost of every card in your hand by 1. Used in conjunction with 'Break' means you can use activate its ability multiple times. It's best used with a full hand and in the Integrity deck. When a card is brought back from the board with cards such as 'Break' or Doggo after having its cost reduced, their price will revert to normal like their other stats. If a card such as Flowey has their cost reduced by Lesser Dog and then is put back in the Deck, their cost will also revert back to normal.
