High attack damage monsters and good synergy with the other cards to combo easily.
Mostly relies on offensive strength, difficult to go against higher attack monsters if they do fusion or ritual summon.
Might be difficult to summon out grarl due to the requirements needed.
Relying heavily on wonder balloons can be bad since it is susceptible to spell destroying cards after you already discarded your cards.
How to use the deck
Calling out the guardian:
Arsenal Summoner can be used to search a Guardian Grarl through his flip effect, it is recommended to only do this when you don't have another grarl in your hand since you will not be able to summon them if you have 2 or more in your hand unless you use wonder balloons.
Lower and Lock:
Gravity Axe can be used to lock down their monster's position, this is very useful if they have several monsters out before you start lowering their attack by using wonder balloons, which can also be used to either summon your grarl and/or increase Flash Assailant atk
Throwing away unused ones:
Since speed duels can be over pretty quickly, this deck focuses on the cards that you get early on and empowering them while also weakening the enemy through wonder balloons. Sometimes it's better to discard the unused ones through Wonder Balloons to get an early advantage.
