I will warn you that you'll need 3-4 Perfect Guards for Spike Brothers cause since it's an Aggro deck it lacks alot of defense to keep itself going but it's pretty good for putting alot of pressure on your opponent though with Dudley Dan and Dudley Emperor. If you're going to run Spike Brothers make sure you run 8 Critical Triggers as well.
Fortunately for you Spike Brothers isn't quite as popular Anime-wise compared to Kagero so
Cheer Girl, Marilyn (Spike Brothers Perfect Guard) I think is going for $15 a piece or lower instead of $20 or higher like Wyvern Guard, Barri in Kagero. Both Kagero and Spike Brothers are really good so If you want get the Kagero deck for $135 and get Spike Brothers over Nova Grapplers you can.
