I think he's referring to Riptide Shapeshifter allowing you to basically tutor creatures into play, assuming you build your deck correctly, rather than anything about Lazav and the Shapeshifter working together. Or perhaps he's just going to name Shapeshifter, and see what comes up.
Along with any chance of blocking. I'd prefer a card like Ghostway.
Screwing up one wrath is a decent enough trade.
Unless your creatures have vigilance, Teferi's Veil really doesn't stop you from blocking any more than the fact that you already attacked does. Granted, it also doesn't protect the dudes that don't attack from wraths, but that's a small trade for something that also allows you to wrath on your own turn without missing a beat.
Honestly, this will probably be addressed in the FAQ when he comes out, but I think I lean towards the "he'll die as a 5/5 with four damage on him", though I can see the argument that he'll die before he gets the +1/+1 counter. I don't think lethal damage checks both before and after it's been modified, though this is the first time they've had to define it.
I could be wrong, but I am pretty sure you are incorrect about that. If I am playing three players and one person hexproof's all of their stuff, it just means I don't destroy anything they have; I still get to target the other two and the Sylvan Primordial still comes into play; I just don't get a forest off of the one person with hexproof.
If you can't choose a target for one player, you don't get to choose any targets, because Sylvan is missing the "up to one." An another example of similar templating is Decimate, where you have to have one of each to target to be able to cast it at all. You have to have one non-creature permanent for each player to target, or you don't get to use the ability at all.
That said, they only very rarely use the second templating, specifically on Mossbridge Troll and this card. And looking at those two cards, it's very easy to grok what happens for newer players: Whenever this thing would get killed, regenerate it. If something makes it so it can't be regenerated, it dies. The complications really only come up when you've learned enough of the rules to know what a replacement effect usually is, but not the specific exceptions and how they work.
Edit: This particular card still has some issues I'm not sure about with things like Incinerate and dealing exactly lethal damage, but that's something that can be cleared up fairly easily eventually.
Powerful, and still fulfilling red's identity. Similar to Rummaging Goblin and Mad Prophet but repeatable and more lasting power as an enchantment.
Typically, that's been in blue, but it's definitely a part of looting they may be thinking of moving out of blue into red. That said, I'm not sure I'd want to 'use up' our YMTC on such an obvious design. Unfortunately, I'm not really sure of a more unique way to do the effect.
Edit: On the other hand, the card idea above me is so far out of the color pie, in addition to being pretty terrible. Plus, flipping a coin is never a cost... you flip a coin as part of the resolution of the ability. As has been repeatedly stated, Red is supposed to have trouble with high toughness creatures, enchantments, and drawing cards. It's not supposed to get a cheap enchantment that breaks the entire color pie.
I don't understand how you could underestimate this card. If it is printed as has been revealed, it can only get taken out by 3 oft played removal spells in the environment, Terminus, Angel of Serenity, and Oblivion Ring. Terminus takes out anything anyway, Angel of Serenity is a 7 mana creature, easily taken care of by BG, and Oblivion Ring is easy for BG to deal with. (Abrupt Decay etc.). Any other removal spells just gives it a +1/+1 counter.
Ahh, but remember that with the red half of Desperate ravings, you have to spend the card itself to get two cards, and discard one. Therefore, it's an example of card filtering at best, until you add blue.
From my experience, the only thing I really dislike about Sylvan Primordial is the fact that you are required to hit players who are already suffering and have weak board positions.
That's probably my largest beef with it, though I understand why it's worded that way. Amusingly, it also means that someone can counter the entire triggered ability of the Primordial with a Simic Charm in response to it being cast. Since they can't target any of your stuff, they can't pick enough targets for the ability, and it can't get placed on the stack.
Anyways, I agree that a large portion of the dislike for Primordial comes from the "god hand" scenarios, combined with lax mulligan rules. If people are consistently getting "Entomb into Reanimate," I'd seriously consider looking at how you, as a group, mulligan. Partial Paris with one free really exacerbates this type of problem, as the amount of initial hand sculpting it offers is absurd. Regardless, look into how often it really is causing a problem, and how often it just comes down and kills a few things while ramping.
I think the point of what he was saying, and I could be wrong on this, was people submitting ideas like "sac something: draw a card" in red, or such not, where the thing you're saccing for is a permanent resource. Red sacs things for temporary resources, typically mana of some kind. And that sort of ability can be very dangerous on an enchantment, or very underpowered. It typically goes one way or the other, with little middle ground.
It does depend on whether or not the store uses the "if someone combos out, everybody else keeps playing" rule, though. Then quick combo out gets you lots of initial points, but leaves the other players able to try and catch up with you, without you being able to interact.
To be fair, it's completely possible to aim lower. For example, I could campaign to create

And Mutilate and Detention Sphere and Tragic Slip and Liliana of the Veil...
There's quite a few that take care of him, so no, the sky isn't falling.
