You should not be running the CB1 +3k at all in this deck, it does not do anything for it, and if you have to ride it then you're not in a good spot. The Break Ride isn't the best no, but it provides a lot more than the 10k CB1 +3k attacker. It's an 11k base, and when under Zerachiels LB, it hits crossrides by itself, or against 11ks, you can hit 26k boosted by a Hesediel. With the 13k attacker, you hit 28k with the counterblast. Crossrides are not that prevalent in today's meta, and hitting a number as high as 28k isn't needed. And again, if you ever end up riding this card, well your deck just lost a lot of synergy, and unless you're opponent misplays, and you get a lot of triggers, you'll probably lose. The card just simply isn't that good.
