I love to take cards that are kinda meh and watch them punch above weight in a certain type of deck. Not necessarily make them good, but make them do more than someone expects from them.
That is the best you can hope for here. First -- against the wrong kind of deck, this does nothing.
You are using Mongoose as your sentry breaker and I'm running Ichi 1.0 so you pay 6 before and after to break all subs. Or you are using Corroder so I'm costing you 1 more per run to break Eli...
And don't even talk about Yog.0 and Viktor 1.0. Ugh.
So mostly it makes runners who didn't plan well suffer -- Cerberus "Lady" H1 against Eli or trusting Au Revoir to be your whole econ engine with no back-up plan for when the outermost ice gets Rezed...
In that sense, call it a meta call. Everyone is using Lady lately with no back-up? Give Eli some teeth.
