I would almost always loose to an opponent in a Explosive Weaponry rule set like in the example below:

Loosing gets me frustrated so I reviewed the Explosive Weaponry battles that I can find and noticed that the winners' cards are most likely to be faster than their opponents'. It will eliminate one or two cards before the round ends. In doing so, opponents' card will have lessen attacks that can affect your decks.
After snooping, and an Explosive Weaponry battle came out. I tried my best to put out the fastest card that I can. And... I won!!! :D
