Here is a sample deck from Youtuber DifferentFight. This is a Nova Grappler deck that he used in order to get to Legend in Ranked Fight in 5 days on the JP server. One of the featured cards here is Asura Kaiser, which lets you stand one of your rear guards if your drive check reveals a Grade 3 card.
Lion Heat is a high-powered card that has an effect when it hits a vanguard, As long as they have C Blast 2, you can stand 1 of your other rear guards for extra support. The similar effect is also available for the Gold Rutile card.
Death Metal Droid can be used for an extra boost in case opponents get higher power. This unit has the ability to get +3000 Power.
Transraizer has the power when placed to let you reveal the top card of your deck. If the deck is Grade 2 or less, you can call it on the field, and if not, you can shuffle your deck. It’s a good way to get support when calling.
Battleraizer is your Grade 0 card, this lets you draw a card when boosted and have other added effects.
Thanks to your Asura Kaiser card, you can have increased chances of standing your rear card during a drive check. The Lion Heat and Gold Rutiles cards on this deck let you make rear cards stand which let you deal additional damage. This deck is focused on that extra power that you can get, as long as you're able to line up the correct rear guards to support the front liners. Death metal droids let you form columns that can reach up to 20k power quick. With the Transraizer, you're able to get an extra call if you get the correct card, which helps you in case you need more calls and Battleraizer can let you raw a card as well. Take note though that in order to succeed, you'll have to be careful with positioning your rear guards.
