For linking a card to Gatherer without writting the name of said card for readers, use the autocard brackets together with and equal sign and right the name of the real card. Then put the message you want inside the tags, like you would do with autocarding. Like this:
I like storm crow because I really like crows in real life, as an animal, and the card isn't terribly stupid, but packs a good deal of nostalgia and also a chunck of the game's history. So it's perhaps one of the cards I have most affection to, but not because "lol storm crow is bad hurr hurr durr".
Oh, it's a brilliant plan. You see, Bolas was travelling through shadowmoor, causing trouble, when he saw a Wickerbough Elder with its stylin' dead scarecrow hat. Now, Bolas being Bolas took the awesome hat and he put it on his head, but even with all his titanic powers of magic he couldn't make it fit. He grabbed some more scarecrows, but then a little kithkin girl asked if he was trying to build a toupee. "BY ALL THE POWERS IN THE MULTIVERSE!" he roared, "I WILL HAVE A HAT WORTHY OF MY GLORY." and so he went through his Dark Lore of Doom (tm) looking for something he could make into a hat that would look as stylish on him as a scarecrow does on a treefolk. He thought about the Phyrexians, but they were covered in goopy oil that would make his nonexistant hair greasy. He Tried out angels for a while but they didn't sit quite right. Then, he looked under "e" (because in the Elder Draconic alphabet, "e" for Eldrazi is right next to "h" for Hat) in his Dark Lore of Doom and saw depictions of the Eldrazi, and all their forms. "THIS SHALL BE MY HAT!" he declared, poking a picture of Emrakul, "AND WITH IT I WILL USHER IN A NEW AGE OF DARKNESS -- ER, I MEAN A NEW AGE OF FASHION!"
And so Nicol Bolas masterminded the release of the Eldrazi.
I think the rings are cute. They are weak, but they're very fun. I remember when I first started playing, cards like this could eventually make a creature too big to do anything about and it would then wreak havoc. I can see them being relevant in multiplayer, especially the red ring (red sometimes has a dearth of long-term viable cards, depending on the format you're playing).
And I think their applications with multi-colored creatures are super cute, if you decide you want to "break the rings". I don't think they'll ever be awesome, but I think they look fun.
I think he's underestimating Ring of Xathrid , especially in limited. As far as I can tell there's not a single piece of removal in the set that can effectively stop an X/2+ regenerater. Murder , Day of Judgment , and Searing Spear all fail. Actually, I lied. Pacifism and Oblivion Ring can both deal with the creature, but the 1 mana to move thing means that it doesn't matter. I could see Ring of Xathrid on a Tormented Soul quickly becoming a serious problem for your opponent.
I only wish they had flavor text. Something cool could have been to use one sentence that mentioned all of them and split it up among the five. Scince Stf vanished, there don't seem to be any vorthoses anymore...
