Well, i think your aim should be to create the following deck (effevtive and strong):
77j 77j 77j 77j 7t4 7t4 7t4 7t4 7t4 7t4 7t5 7t6 7t6 7t6 7t6 7t6 7t6 7t8 7t9 7te 7ta 7ta 7td 7td 7td 7td 7td 7um 7um 7um
/EDIT: "???" = Dark Pendulum
alternative (situationally even stronger, because its mono):
7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t5 7t6 7t6 7t6 7t6 7t8 7t8 7t9 7t9 7t9 7ta 7ta 7tb 7tb 7td 7td 7td 7td 7td 7td 7te
(you could remove a steal and the shadow to add more devourers/pests, depends on what or whoom u fightin against)
I really hope this helps you.
