Blaster Keroro although what seems to be just a funny character from Sgt. Frog, is actually a viable card. This card can be used in Blaster decks or decks which incorporate Blaster cards and make use of Wingal Brave . When Wingal Brave boosts either a Blaster Blade or Blaster Dark , the 14000 attack of which it's swinging for can make an easy guard for 10000 based Vanguards. However, Blaster Keroro when having more amount of cards in your hand than your oppenents allows you to attack for 16000, a perfect number which can be annoying to guard even for 11000 based Vanguards. Blaster Keroro is also a searchable unit with Wingal Brave.
