Say goodbye to half of your deck as swarm Lilithe rams her cloud of wraithlings into your general and then banishes the Ruby rifter 
Monthly Card Preview: Ruby Rifter
Well unless you put Blistering Scorn in it xD
I really like scientist better than this. I could see it being used in a face magmar deck or something but most generals can proc scientist with their BB spell without taking face damage in addition to whatever targeting cards they have, so it’s more than likely you can proc it multiple times in a turn, where as with this you usually only get 1 draw from going face unless your deck is built to damage your general.
It’s not bad though. I just think scientist edges it out.

I think you are wrong 
Ruby is better is the vast majority of the situations , but the biggest edge ruby has over the scientist is the fact you can drop at 6 mana and get immediate value out of it while with the scientist you either need to wait an entire turn or have some mana left over. Ruby is going to be very good in any deck that want to smash with the general anyway (mainly vaath), while the scientist didn’t see a lot of play since its release.
I would agree with this scientist is a 7 drop in reality,Ruby Rifter almost always 6/6 and draw 1 card when you use it.
