Tell me possible changes, R&C plz :/
It's a good deck, but because of how the scoring system weighs so heavily in favor of low-level cards you might want to downgrade Jakson or Coby to a 3*, preferably one with good damage.
Imo ... get rid of both Jakson and Coby and replace them with Carmen and Westwood.
You have to remember that the only reason why the Sentinels are so popular now in the DTs is because how the current scoring system favors low-star cards and almost every 2* & 3* Sentinel can hold their own against other heavier cards.
"but what about the possibilities of 2HKOs?" ... in that case, Copper Cr/Sammy for Hawk or simply play Uppers.
Luke can be opted out for Morgan (I hate that "3" damage)
Try running Morgan, Westwood, Tobbie, Lehane, Carmen, Martha, John & Sammy (it got me 4th with 422 bps, hope you'll do better)
gg ... always
Sammy makes all of those cards ko, genius
