This card is very strong, basically 6 mana 6/6 that draws you a card and gets out of control if not dealt with.
The only big downside is that it is awkward when you are behind because you most likely want to get away rather than attacking with your general. On the bright side your opponent will most likely have to take down the ruby rifter before attacking you which is something.(unless you are very low and he just has lethal)
However I find the design uninspired IMO.
That’s what I see 4 monthly neutral Magmar cards,I have start looking at what cards to drop from my current list.Warbeast finally has competition again
Makantor doesnt have competition, its more likely to have both jajaja
Great synergy with blistering scorn and elucidator. Effect will be great in Magmar, could be a counter to Faie’s bbs. Great late game draw, but I’m not sure it’s great by itself as a draw mechanic. Overall superb card ^^
Agree with that statement 100%
I have to say that the new cards seem quite powerful and this is no exception. This can come out as a 6/6 and attack next turn for 8(or 10 if your opponent attacks your general). It can also come out on turn 2 for second player and turn 3 for first player is using Magmar or Abyssian. Reclaiming the card advantage immediately.
Why, oh why is this card not named “Sworn Fomentor”?
Yeah another “Sworn” card would be great.
Assuming you can immediately proc this, it’s a 6 mana 6/6 that cantrips. After that, there are three possible scenarios:
It’s immediately removed. Which is fine, as it usually requires either trading, a transform spell or two damage spells to get rid of a 6/6.
You are being milled. Assuming this card draws a card the turn it is played and you automatically drawing at the end of your turn, the enemy can easily mill you if you had more than 3 cards after playing Rifter and they are in a position to attack your general with multiple units. Songhai is especially scary with 4 Winds Magi/Bloodrage Mask, cycling through their deck while milling yours and then transforming Rifter into Panddo.
You get consistent value over the following turns. Aka the “win more” scenario.
In typical gameplay, we can discard the third possibility. So in order to get the best value out of Rifter, you need to be in a position where you are either low cards or the enemy is low on board and does not have a lot of out of hand damage.
the perfect card for people who never ever play artifacts, use up their entire hand, and hate shadow dancer and 4 winds magi
Not good when you are losing.
You need to trade with your general which could get you killed more easily.
No immediate effect on board.
The scientist looks better, providing safe draw. If not removed threatens to win by card advantage over time.
Ruby rifter is risky card draw. Less card draw threat since general is lowering health to proc effect.
Combos pretty well with Blood Taurus and Chakram though.
I can see this card getting some play in Kara decks, the draw is pretty useful and with 2 BBS buffs you can summon a 8/8 and still draw a card so I guess it has some potential.
It’s also one of the coolest looking cards in the game so we can’t let those animations go to waste… Right?
And with 3 BBS the card will be a 9/9, yeah this is what Kara BBS does incredible isn’t it?
Say goodbye to half of your deck as swarm Lilithe rams her cloud of wraithlings into your general and then banishes the 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.
