Plus, if your opponent is at 4 life and you have 8 mana, it's GG.
You'd need 9 mana to end the game right away, in that case. If you're at 8 mana, the land you Awaken will be tapped. Not to mention, if they have any land-dudes of their own, you might not be able to attack through anyway.
SBAs aren't doing anything here, just BB's own triggered ability. There is a time during Juxtapose's resolution that a player who is not BB's owner controlled it, so the ability will trigger. The trigger will then wait until a player is about to get priority before being put on the stack at all (like all triggers do, they're so patient). In your set up, by the time the BB's trigger resolves, it'll be telling a player who doesn't not control it to sacrifice it. This can't happen, of course (players can only sacrifice permanents they control), so they won't sac it, and thus the part of the ability that says "if you do" won't and can't happen.
So, that's the long winded way of saying that yes, you're right that BB won't actually blow up and/or do damage to anyone, but not exactly for the reason you've given.
Two-Headed Giant is a Multiplayer variant, you do get a "free" mulligan. You might be confusing it with the play-or-draw rule: normally, in multiplayer variants, the player who goes first doesn't skip their draw step like in 1-v-1, *unless* it's a "shared team turns" variant (which 2HG is, as is Archenemy), then the team going first does skip their first draw.
There are plenty of things with Kicker where the Kicker adds an entirely new effect to it, not just enhances its existing effects. look at all the Battlemages or a bunch of the other creatures with it, or things like Dismantling Blow, Jilt or Illuminate. That's the problem with Kicker, so many other things can be boiled down to "pay more, get more". Many other mechanics in Magic are just subsets of kicker.
It's not completely unheard of for *Free-To-Play* games to not show up on Steam until they're actually fully released (probably because without the need to pre-order anything, there's not necessarily a point for it to be there). I wouldn't take it as any kind of bad sign or anything.
To be fair, Theros as a plane is very much "about" the magic - every durn thing under the Sun is an enchantment! On the other hand, lately we've been to Tarkir which is very much about "war". So it's quite likely that, like every thing else in Magic, there's a pendulum for art style/direction that just happens to be swinging a particular direction that will sooner or later move in a different direction.
Yes, you can. Note however, this will not circumvent having to pay the Commander Tax subsequent times of casting and/or Dashing, as paying the Dash cost is still *casting* Zurgo (as opposed to an activated ability like Deveri's, which does dodge the tax).
In one of my flights, I chose Silumgar and the single FTF pack provided me with... Palace Siege. A bunch of Exploit dudes and being able to get one of them back from the GY every turn is *value town*, even when it's just a single Sidisi's Faithful (with a Dutiful Attendant as backup) - but if it's a Rakshasa Gravecaller then hoo-boy, do you get dirty looks from your opponent.
In another flight, my Kolaghan box provided me with a total of *three* Ultimate Prices, and a bunch of other removal and nicely efficient beaters, so... yeah. At my LGS, BR decks over-all did seem to do more consistently well than the other clans.
No matter what amount you're actually paying (or not if you're getting a freebie!), the specific phrases "Mana Cost" and "Converted Mana Cost" *ALWAYS* mean the numbers and symbols printed on the card in the upper right corner.
Pre-Mending 'Walkers had their powers reduced by the Mending (that's why Bolas keeps trying to find ways to get his powers back). The only reason some of the pre-Mending ones are still around is because they had *separate* methods of immortality apart from their Spark: Liliana's demon-pact, Sorin's vampirism, Bolas being an immortal Elder Dragon, Karn being a magic robot, Venser's access to slow-time water via Johira. The Eldrazi were sealed thousands of years ago; if Nahiri is still alive (and Sorin seems to be assuming she should be), she'd need to be some kind of very long-lived or immortal race or being.
You'd need 9 mana to end the game right away, in that case. If you're at 8 mana, the land you Awaken will be tapped. Not to mention, if they have any land-dudes of their own, you might not be able to attack through anyway.

Or is that not the information you meant?

"Ears." The word you're looking for is "ears."
