Bunbun is a very good card, despite it's appearence. When placed, it will summon a Bun.
The Bun is not something to brag about in terms of stats. It's a 1/1 monster with a cost of 1G (which doesn't matter much, because Bun is summoned to the board right away). With those stats, it's tied with Sans of having the lowest stats, excluding 0/2 cards such as Gift and Lamp.
However, it's Bun's Dust Effect what makes Bunbun so good. As when Bun dies, any Bunbun you have on the field will get +4 ATK. This works VERY well with more Bunbuns, as it may get up to 11 attack just with 2 buns.
This makes Bunbun very good in multiple decks for different reasons.
- Integrity: You can get more Bun's by using Break and/or Cloning on your Bunbun's.
- Bravery: You can place 2 Bunbun's to gain a full board. And if you use Final Charge to make the Bun's attack the enemy monsters to kill them, both your Bunbun's will get +8 ATK, for a total of 11 ATK each.
- Kindness: Bun can increase Bunbun's ATK, and you can increase it's HP with your Spells. This gives Bunbun stats simmilar to Royal Guard 1.
This card works very well with Golden Flowers.
