Hello guys,i have a sentinel deck with which i win mostly dt and dm and i lose in survivor after 2-4 wins and in elo i hardly reach 1100 elo, i never reached it but i was always close. i think that a mono sentinel isn't good idea so i would like to make it half sentinel or start a new deck, i have 20k clintz to spare for an elo deck. thanks
Sentinel are not great with half decks. Cards like coby and john can't be used and those are two of their best cards. I almost never see sentinel half decks. As tiger said, they are also too vulnerable to soa.
You're a young player so I suggest to start out with an easy clan like rescue. Good luck.
