This is a thread of another player who was successful when they asked a similar question.
Mono Sentinel or Half Ghostown/Attack manipulation clan
Deck: Carmen Copper Cr John Lara Hate Martha Tobbie Valentina Ld #ZRobbie
They mainly got first place due to winning rounds, low star count and KO approach with Copper Cr.
However, I am not sure what your budget is or what you can play within the Sentinel Clan.
I can recommend Aviria Ld on the exception you do not have Copper Cr. However Aviria Ld does not have that virtual 9 Power compared to Copper Cr.
If you cannot afford Copper Cr, on the bare minimum, try getting Havok or Pavel. If not, look for another alternatives for Copper Cr or any other card you cannot afford and change your card combinations to less than 25* to get more points in DT.

I've run this Carmen Copper Cr John Lara Hate Martha Tobbie Valentina Ld #ZRobbie deck with some success, but what do we do about John? his high potential power & 4 damage are part of why this deck works, so who is his replacement? Thomy?
