Beck is likely to get banned in modern. It's nuts -- the one mana difference between it and glimpse is significant, but so is the ability to draw cards by chaining through token generators. I can't fucking believe they printed a Glimpse of Nature that works with tokens.
'Loser Affinity' will be a deck for a few weeks. I already took my ravagers out of the trade binder.
Ral Zarek will see some standard play for his -2; RUG control might become a thing. The +1 is hard to rate, but I'm guessing the tap ability is pretty much useless. His ult is fucking hilarious, and will cause him to see WAY more play at FNM than he should. Not a great planeswalker -- he's worse than every other PW he tries to emulate (mostly ajani vengeant) -- but he's still playable. 4cmc lightning bolt + a planeswalker for later, on turn three, off farseek, is good enough.
Compare to how most people used Ajani Vengeant during his time in the sun. Lightning helix a dude, leave the board empty, now you have a planeswalker capable of tapping down lands for a while.
....unfortunately, Ral Zarek ramps and removes blockers instead of keeping lands and attackers tapped. I don't think his abilities are synergistic with each other, and it seems like he's trying to cater to three playstyles at once.
Melek is a pretty nifty 'fair' izzet Commander. Obviously you can do insane things with him, but he won't draw hate like Jhoria or Niv. You could also probably do something ridiculous with him and top in a (casual) legacy pet deck. Entomb, reanimate, dark ritual, seething song, pyretic ritual, rite of flame, animate dead, griselbrand, sensei's divining top to spin to the next mana ritual, scroll rack as a backup top, etc etc etc. You'd need to load the deck to the fucking brim with rituals, but it'd still be fun as a motherfucker to pull off. Just not competitive.

the other cards....
Wear/Tear is pretty nice. Hull breach at instant speed for one more mana, in boros. EDH loves it.
Toil/Trouble is playable. Three mana for a Sudden Impact is below the curve for this standard environment, as is a three mana sign in blood. Give both options and the new mechanic, and you've got a card that breaks open the jund midrange v control matchup pretty hardcore. A three way split card between divination, sudden impact, and "target player loses 5+ life" is absurd.
Jund doesn't really have that sort of reach outside of thundermaw hellkite, and attaching a lategame burn spell to early card advantage is very good card design. The only issue is, Jund doesn't need any more help beating control. It has Liliana. The card is solid, but I'm not sure it does enough or has a home in standard. I still wanna play with it.
VALUE PREDICTIONS:
Ral will not be an expensive planeswalker, but will stay over $15 for most of his standard run due to newb appeal. Expect preorders to begin at $30-40, and slowly fall to 15 once redemptions are up.
If he finds a home that can take advantage of his odd abilities, he might be able to keep a $25 pricetag. I wouldn't feel too bad jumping in at around that price now, as he'll likely be trading for 40 at release.
Beck will peak at a few bucks (under ten), then likely get banned in modern. Expect many combo elves and affinity pieces to make a 10-50% jump in the next few hours/days.
Everything else spoiled is bulk. Render silence might be two bucks longterm, as it's pretty nifty.
