I keep imagining using this on some degenerately horrible creature like Hellcarver Demon or against decks not optimized for Dralnu, Lich Lord, donating it to an opponent, and then forcing all the bad effects on them with it. But imagination fails me here save for the derpiest of derpy decks, so I only ever see it really used as a haste/buff.
Hellcarver Demon, eh? Throw in a Bullwhip and you might have something there.
As mentioned, Oblivion Stone, Nevinyrral's Disk, and Plague Boiler are great bets for wrath-type effects. Yeah, you'll hit your Glissa, too, but that's only if she isn't indescructible at the time. :^)
You'll still get Glissa's trigger on the stack, though. o3o
Which of these cards do you think this new player will be able to "break" more easily?
Depending on what you mean by "break" it's almost certainly T&N. New players tend to shy away from 5-color decks because the mana base in intimidating and the sheer amount of choices they have are overwhelming. Thus T&N is probably the first one they'll cast and end up doing something particularly unfun with, like finding Terastodon+Woodfall Primus and blowing up their friend's lands.
I don't know how many new players you know, but all of the ones I've met will cram their decks full of suboptimal cards to try to get a spell like Coalition Victory to work because new players typically don't understand how manabases or manacurves work, they want to play with as many colours as they can get away with, and, as has been repeatedly stressed, Coalition Victory has "you win the game" right in the text box.
I quite like the cycle of borderposts. Early you can play them like tapped lands, and later you can cast them as ramp, and as long as you're ok with taking your time, the downside to that is opening yourself up to artifact sweepers. My complaint is that I feel if you pay the mana cost it should enter untapped, but I still play these in a few decks.
The Wildfield and Firewild Borderposts were the only mana rocks I allowed myself in my all-multicolour Mayael deck.
I don't know how it is for anyone else's meta, but I hardly ever see anyone play Savage Summoning. It turns any creature you can cast into an uncounterable combat trick.
Honestly, as someone who loves playing with creatures, Humility is the most annoying effect. Luckily it is essentially the only card with this effect. I know its not a keyword, but man does it suck to play against.
The Panoptic Mirror discussion picked back up recently, and it got me to thinking... Can you imagine a world where someone can imprint Coalition Victory on the mirror and make the table scramble to answer it every turn? Whoof.

At last, an excuse to play my Unlimited Edition Nettling Imp!
Yeah, I'm pretty sure the most recent bear we've gotten is Bruse Tarl.
That would be suicide.
Those who do not learn from the debates of the past are doomed to repeat them.

I wanted so bad to fit this guy in my Damia deck. But he just doesn't do enough!
Is this Primer dead?
