You could use secrets for early control, with [[Professor Putricide]] and [[Cloaked Huntress]] helping out.

Meanwhile [[Forlorn Stalker]] and [[Shaky Zipgunner]] help buff deathrattle minions in hand, and [[Terrorscale Stalker]] can take advantage of deathrattle cards on board. None of those are beasts so they won't dilute your graveyard pool.

You could substitute your 1-drop beasts for pirates, elementals, and murlocs - not to mention [[Secretkeeper]]. [[Arcane Anomaly]] could be decent if you're expecting to play a few secrets.

If you could get through those early turns, and get something like a King Krush on board... Then when it dies you play a Stitched Archer, trigger its deathrattle with Terrorscale to get a second Krush. Its deathrattle triggers again when it dies for a third Krush. Then you play a second Archer, a second Terrorscale...

The deck's dream combo of getting multiple Krushes on board looks a bit unrealistic and reliant on godlike draws - sentinel has very weak card draw, and you'd struggle to pack in much neutral card draw. But if the base deck is strong enough, with secrets for control while you buff up your hand with Stalker and Zipgunner, it could actually work. You may run no beasts other than the Krush. I guess you could throw in 2x Charged Devilsaur: 7/7 with charge is almost as good as Krush's 8/8, and its can't-attack-heroes battlecry wouldn't come into effect if you weren't playing it from hand.
