The only thing that would make the Mycostone deck even more amusing to me is the addition of Windborn Muse and Ghostly Prison. Basically, make it so no matter how large your opponent's force is, they can't kill you while you peck away at them with the flying windborn muse.
Alternatively, consider adding red to the mix for Braid of Fire - or run green for Magus of the Vineyard or some of those snakes with triggered mana abilities.
Lots of exciting things to do if mana is turned off!
The obvious combo with Mirror-Mad Phantasm is to play a deck with only one copy of it, but several Clone -like effects, so that when you get that one copy you can clone it, use the clone's ability, deck yourself and win with Laboratory Maniac or anything that can use a full graveyard. (Harvest Pyre plus Stuffy Doll , any Lhurgoyf -like creature already in play, especially Splinterfright because it has trample...) Maybe that's too obvious for this column, though.
Why no Null Rod s in the first deck? More chances to put up the "PMITA Prison", as I call that combo, would be welcome, right? Besides, Stony Silence owes its pedigree to something.
It doesn't have access to white for Stony Silence, but I occasionally (not too often, of course) demonstrate the original incarnation of the combo in a Kaervek EDH deck that...pretty much fits Kaervek well, come to think of it. Card acquisition for that deck can be rather prohibitive in offline play, but 1) this isn't the kind of deck you probably want to be bringing to a table near you and 2) The Tabernacle at Pendrell Vale is a devastatingly effective way of controlling the board once everything goes maximum-security lockup. Certainly much better than Sunscour, for whomever let that bombo slip through editing.
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.
