Deck Total (50)
You don't have to netdeck it entirely but this is the most consistent Lawkeeper Kagero deck out there right now. Your Grade 1's focus around discard and draw with Gojo and Aermo If you get Gradelocked. Kimnara is good as a 1 of but If you feel the need to run more then go ahead I guess. 4 Barri is a must cause your deck will be inconsistent competitively with just 3 Perfect Guards. I ran 3 Halo Shields in my Gold Paladin and it wasn't NEARLY as good running 4 of them in the deck which it does right now.
The Grade 2's are self explanatory, 10k's are stupid good and Berserk Dragon makes for amazing board control. One of my friends runs a Lawkeeper Kagero deck with being able to Superior Ride into Embodiment of Victory, Aleph which is nice but at the same time can hurt the consistency of your deck by devoting specific units of lesser Grades to pull it off but then again If you're running a Trigger Ratio of 4 Heals and 12 Criticals that shouldn't matter. Chu's build runs 5 Draw Triggers because it thrives on drawpower and you should do the same.
Hope this helps and good luck TPZ.
