i made these changes:
-2 battle rage
-2 cornered sentry
-2 dry whisker armorer
+1 execute
+2 slam
+2 eternium rover
+1 whirlwind
.
explanation
even if u setup perfectly for the OTK, theres still a chance of drawing a minion, which will either make for an inconsistent combo or the combo being delayed a turn.
slam – card draw and removal. helps setup for execute
execute – play 2 with slam
eternium rover – even if u top-deck this, u can still play it out before boomship. its also more armor
whirlwind – can be used as grammosh enaber, but mostly will be used as a board clear against aggro and extra utility w acolyte of pain and eternium rover
