So, if you’re gonna stick with this, then I say play whatever you feel is best for you, but if you’re looking to beef this up…
As was said earlier, cut down on those two drops. Too many and you’ll be tempted to use them all at once when it’s convenient - too little and you’ll never have a thing. If this is a wall deck, take advantage of the wall system.
Spells
Bone chill is fine, so you can leave that where it is. Chromatic cold is in a fine spot also, so that can stay at three. Frostfire is a tricky one… At times it can be a valuable asset, because you CAN swing with walls, and most people forget that, and wind up leaving them alone, or standing too close and gettin’ hit wit the okie-doke, and then they’re left with a 3/X wall will then have to be solved with either dispel, forced position change, or hard removal. Other times, it can be a nice big clunk in your hand, simply because you somehow goofed up and are left with no board presence. This one is on you. If you’re gonna stick with those spines I see, then keep them around, as Hearth-Sister is gonna be a friend of yours. Blazing spines is either an all or none in my opinion. Yeah they make a little board presence, but they don’t stick around long. The magical ninja squad, sand-nigs, and MAYBE the mirror might fear that, but everyone else? Mmmm, food. Cryo @ three. Always. Rest of argument moot. Avalanche… You gotta be careful here. Cut to one. It’s situational, VERY. If they don’t care about your infiltrate, then you got a nice bit of clunk there. Aspect… Hmmm… let me get back to you on that.
Minions
I don’t see a third snowchaser… why? That little annoying bastard is your best friend in an infiltrate-friendly deck. Undying minion that can be searched? Turn 1 Bonechill > Chaser? Uhh… fix that. Cloaker… eh. I say two, but if it works for you… White Mage is ok here. Hearth @ three if you plan on keeping those spines. otherwise 2. No Shiro. I don’t see Kara I’m-going-for-the-Tolbelistein Winterblade here. I mean, having a wall gain a little bite each turn is cute, but that ain’t gonna save you. A little less Glacial. He comes out of a cryo if you want it that bad, and if you don’t have board - which is a problem for us - then yeah. I kinda have a thing against primus. I’d say play him if you were playing Polarity, otherwise, No. Draugar…? There are better options. If this is Infiltrate, you want more infiltrate. Oh, where are your sisters? Infiltrate under a Maya is always a plus. If this is infiltrate, you need more things like Groot, repulsor beasts, maybe a ghost lynx, hell, even Paddo if your balsy… Things like that. The Veyspr thing… it’s nice, but don’t lean on it… not enough support. Now, you can get away with not playing saberspine… I’ve done it. HOWEVER, It does ruin butts if you need it too. Your call.
Tl:Dr
More snowchaser, less spells (-1 frost, -2spines, -1(?)Avalanche, -1 that mountain thingy… there are better options, and that thing is expensive…), no shiro, little less sister, a lot less primus, none of that Draugar stuff (He’s just bigger Wolfmaster IMO), and I am Groot. Toss in some odd stuff like repulsor, Bloodtears, stuff that moves minions, maybe mesmerize if you wanna fool around with people (forcing them into a BB makes people mad as hell!), or get them off that mid line for an avalanche setup… Beyond that, I got faith in you.
You got this bro!
