Keeping the Peace

A 4/4 for two mana? Sweet. In white? Even better! Without a double-white casting cost? Where do I sign? That would be the logical reaction if Loxodon Peacekeeper had no text box. But alas he does and because of it, he blows and is the subject of this edition of "Bad Card Made Good."

Forget the Peacekeeper's drawback and focus on its name for a moment. It's a peacekeeper. Not many decks are going to attack headlong into a 4/4 in the early game. Add a few walls to the mix and you're in even better shape against any early onslaught.
Next, enter the Loxodon Warhammer. Asides from making sense flavour-wise, it can get you a 7/4 trampler attacking on turn four. But wait, the mighty hammer gives you life, which is going to send the Peacekeeper in search of a new home. S'all good; you still control the equipment so you'll stay high and dry, plus we'll add some means to get our buddy back for more.

You'll need to ensure that the Peacekeeper has haste when he returns home, be it on your upkeep if you're lower on life or by using Brand. Anger's a better ticket than Lightning Greaves, since we'll still want to target the traitorous elephant.
When it comes to the big finish, there are no shortage of options here. You can rupture an equipped Peacekeeper to deal seven to the world. There's also fling. But best of all? Swinging with the Peacekeeper and letting him head to the opposing bench so you can hit him with Cinder Cloud, dealing seven to your foe's skull if he's equipped. Your friend will be stunned when your "Lox" turns his life total into a bagel. ALL CREAM, NO CHEESE, BABY!

I Think, Therefore I Am

Maybe tinkering with Un-cards is kind of cheating, since there are no end of rules they break for the fun of it. That said, I think we have a very unusual scenario that you wouldn't expect to be able to achieve, with Yet Another Aether Vortex. With a tricky little scenario, it can be in play simply because it says so.

Even if there are no permanents in play, and no cards in any player's hand or graveyard, Yet Another Aether Vortex can be face-up on top of your library, as well as in play. This may not seem possible in a vacuum, but consider this: you have a copy of Yet Another Aether Vortex in play, which naturally reveals the top card of your library, being... a second copy of Yet Another Aether Vortex! So the one in play makes the one on top of your library count as being in play as well, making its abilities active just as any other permanent's would be. But let's say you then play Renounce, sacrificing everything you've got except for the Vortex on top of your library. Now it is your only permanent, and it's only still in play because it says it is. "The top card of your library is in play." "Sez who?" "Me, the top card of your library!" Its ability keeps its ability active. Sure, when you draw it next turn the party is over, but whoever saw that one coming?
