11 Spell Pierce This is a counterspell that opponents can easily play around if they know you have it in hand

Whereas Aetherflux Reservoir was more of a slow grindy way to win (unless you have Metamorph), Corrosion was more a swingy sudden combo win

On top of that, I think Mono-Blue Aggro is actually pretty good against the current iterations of Esper Control, unlike in Ravnica Allegiance Standard where the matchup was a lot tougher and I valued having access to a planeswalker out of the sideboard, so Im not too invested in the idea of a dedicated sideboard card for that matchup anyway

That's pretty nuts and I'd honestly like to see cipher return in a future set
