yea the fact that BLS is more dead draw then anything is not worth him in thhe build. You should try dino build for sure. Keep the veilers they are more useful then the thrashers and BLS. Here's my build That I have been using for many months now.
this is the ideal build, except for I play 3 evilswarm bird guy (mind spaced idk) instead of 2 veiler and 1 seven tools.
yeah, bls isn't good in this deck, and also, i would only play 3 normal monsters to up consistancy.
