Here is a sample deck from Youtuber DifferentFight. This is a Kagero deck that he used in order to get to Legend in Ranked Fight. Here he has 4 sentinel cards, as well as 4 blockade cards. If you check the Blockade Card, you’ll see that its effects let all of your opponent’s units lose intercept which provides an aggressive playstyle.
The Draconic Overlord card lets you get 5000 Power as well as Drive -2. You get the when hitting a rear guard which makes you stand it.
The Vortex card provides you with a high-powered card that gets a boost until the end of your turn. Alternatively, you’ll be able to have the option to retire 3 of your opponent’s rear guards when the conditions are met which is similar to the main function of the Berserk Dragon card.
For the Grade 0 card, you will use Liard Soldier, Conroe. as it's a strong card which you can maneuver and retire when needed.
The Blockade card is important due to the amount of power for its base has, this card enables you to make your opponents lose their intercept which will let you deal damage faster. Intercept prevents you from dealing damage to their main vanguard and forces you to hit their rear vanguard instead, but with blockade this will negate that. Having these cards as well as the other supportive cards on your deck gives you the aggressive advantage since there aren't much cards that can counter this. Your other cards can get boosts, which help you with overpowering opponents and securing the damage that you need to deal with. However, take note that your opponent can place a G2 card at the front since they won't be needing to intercept.
