"Mega Blast" (メガブラスト Megaburasuto) is an official term introduced in Booster Set 1: Descent of the King of Knights which refers to an ability's cost written as "[Soul Blast (8) & Counter Blast (5)]". After Martial Arts General, Daim was released, this kind of cost is currently discontinued. G Booster Set 7: Glorious Bravery of Radiant Sword introduced a series of cards which have skills similar to that of a Mega Blast, as well as Snow Elemental, Hjaco which is designed to support cards with Mega Blasts or similar skills.
Normally, paying five Counter Blast means you cannot use any other abilities that need to Counter Blast during the game. However, there are methods that can help you Counter Charge, therefore giving you the chance to use Mega Blast in a deck that utilises Counter Blasts. With some luck, a heal trigger can help recover damage for you to use.
All cards so far with a "Mega Blast" cost follow a certain pattern, namely;
- Grade 3 cards whose original power is 10000.
- Have a (VC)-only ability which, at the beginning of your main phase, Soul Charge (1), then an additional effect (commonly giving the activating unit +2000 power until end of turn).
- Some of them have other abilities, such as CEO Amaterasu.
Originally, the Mega Blast cost can be paid while the unit is on both (VC) and (RC), but starting from Booster Set 6: Breaker of Limits, new Mega Blast costs can only be paid while the unit is on (VC).
