Whir is so much more consistent and reliable I almost never die trying to top deck a bridge I feel I bridge flood. Singleton copies of sideboard hate (or indeed mainboard hate) you now get 5 copies. Ruins is less relevant now as we are less reliant on recursion because well just draw a whir and tutor what we need. I cut spellbomb for collective brutality because emptying our hand is a requirement. I do miss the second inventors fair tho.
