Lets begin with the story behind this deck, for starters, this deck didn't start out as Red/Blue, it went from Stonescar Blue to Rakano Blue to even Praxis Blue. After trying all of these it hit me like a ton of bricks, why not just make it 2 colors? With the new additions the new set has brought us, Red and Blue have increased in power substantially.
What is the point of this deck? How do you win? Well lets start at the core. This deck is a control deck at heart, given its color combination it is a reaction heavy deck. A key to winning with this deck is understanding what cards you opponent is playing and which cards you should be answering and when you should hold up spells. The win condition for this deck is none other than Knucklebones. Now a lot of people would say "Man why would I replace my deck with a bunch of trash?" SAY NO MORE BECAUSE I HAVE THE ANSWER! Basically a combination of card advantage from drawing 2 cards per turn and being able to play cards from all 5 colors with no drawbacks has its perks. It has a very surprising amount of perks. Now when do I play Knucklebones? When do I know it's time to unleash the beast? Well, Ive been running the strategy of trying to have 3 or 4 good removal spells in my hand when I go to play knucklebones. Depending on what you play against really tells you when you should play it, for instance, against agro, sometimes you never want to play it and sometimes you want to play it immediately, it really comes down to how much pressure they have on you at the time. Against Midrange decks, having a good counter spell and a couple removal spells is a good way to assure a good knucklebones experience. Against control you want to play it immediately. With control being so prominent lately, this deck really strives as it can always win late game against control because it never runs out of gas late game. I suggest never playing knucklebones before you have 8 mana as it can really mess things up sometimes.
Levitate - Cheap draw spell with possible late game use on knucklebones creatures
Permafrost - One of the better blue removal spells, great at handling dawnwalker and other units with annoying death effects (MAKTO)
Torch - Lightning bolt, nuff said
Backlash - This card feels unbelievably powerful in this deck because more often than not you can hold up this spell on your opponents turn. Great against smuggler's stash and other big spells
Kaleb's Choice - Weapons can be a tough matchup for this deck so it helps to have a card that can remove those pesky demons. It also doubles as a counter spell making the card efficient and well rounded
Lightning Storm - One of the better mass removal spells, great at dealing with token decks and the likes
Lightning Strike - In my opinion, an under appreciated spell in blue. Not only does it handle units with up to 4 toughness but it also deals with cards like Sword of Icaria, and other Relic Weapons, truly a great removal spell.
Piercing Shot - So I'm called crazy for running this card in a deck but it is shockingly good in the current meta, think about taking out a 2 health unit with warcry and a 3/2 relic weapon at the same time. Overall I think people are showing more appreciation for this card and it is certainly good at handling the current meta.
Rockslide - Hands down one of the best red/blue cards out there. No longer will we have to waste torches on Initiate of the Sands or Oni Ronin
Wisdom of the Elders - Incredible draw spell
Furnace Mage - A card that fell out of the meta but I believe to still be very good. Answers chalice, weapons, oathbook, equipment, permafrost, obelisk. Oh hey, that's the whole meta right there.
Rain of Frogs - Someone asked me, why 4 rain of frogs? I hate Makto, that's why, I also hate dawnwalker, and Rakano plate and so on. Not only do you turn it and every card of that in their deck to a frog but you also get a massive amount of information. Its one of the only cards that lets you see basically their whole hand.
Obliterate - Stupid good card, great finisher at times, good removal in general
Knucklebones - KNUCKLEBONES!!!
Molot and Nakova - A solid late game answer to a large board when paired with a torch or rockslide, more of a last resort kind of card, easily replaceable with another furnace mage.
Mulligans - Cheap removal and card draw is all you want to see in your starting hand. This deck doesn't run seek power so keep a 3 mana hand or more, never 2 or 1.
Cards to avoid in starting hand: Anything cost 4 or greater.
