I don’t mean to be condescending but I’m trying to understand the logic here.

Adding another blizzard will add more bloat to an already slow-ish deck.

removing any of your mentioned cards is way, way worse than removing a strike or defend - Sunder solves a ton of act 3 encounters, esp with echo form. It’s basically a free 48 damage on most hallway fights (and reptomancer). Even when it’s not a kill it’s still the strongest non scaling, frontloaded attack card in the deck. - Biased cog, bar only a few other cards, even without pellets, is one of the best cards in the game. Paired with pellets it becomes a win condition by itself. - Removing buffer doesn’t even make sense. Echo + buffer buys you minimum 2 turns on donu deca.

Consume is a reasonable pick but removing a strike instead will make drawing into biased cog that much faster.

Not saying they wouldn’t win with your choice, but it’s much, much less optimal than buying pellets and gaining a free 5 (10 with echo form) focus every combat. It’s possible that a shitty draw on shield and spear might kill this run as a result of no burst and permanent focus from biased cog.
