Rules Gurus, take your positions!!!
I sacrifice my Academy Rector to Goblin Bombardment, putting one damage to Morphling on the stack. I go fetch a Pattern of Rebirth, which I then place on my other Rector. Sacrificing the second Rector for a damage to my opponent, I fetch a Spidersilk Armor and Rector #3. I sack the last Rector for another damage to my opponent, and Trechery a 5/2 Morphling from my opponent!. All damage resolves, and I am left with the 'phling! Wheee!
Better yet...
I use Yawgmoth's Bargain to draw 19 cards, putting me at 1. I tap my City of Brass for a single Black mana, putting the City damage on the stack. Then I Dark Ritual four times, adding 8 mana to my mana pool, one of which is used to cast Culling the Weak, sacrificing my Rector and adding 3 more mana to my mana pool, putting me up to 11 black mana. I use six of that to activate my Planar Portal, searching out a Serra Avatar (1/1). I then use three more mana (leaving me with 2 Black mana floating) for my Belbe's Portal to put my Serra Avatar into play. It's a 1/1. Now my Rector sacrifice triggered effect resolves, I remove Rector from the game, and go get a Flight, which snaps onto my Avatar. The remaining two black mana allow for a second Culling on a random creature, leaving me with 5 mana. Four Ebony Charms later, Serra Avatar is a 5/5 flyer, and my opponent is at four less life. Finally, my one remaining Black mana is shunted through my Skyshroud Elf to White, and I play Ivory Charm, giving all creatures -2/-0.
I take the single damage from City at this point, and I declare my 2/4 flying Serra Avatar as a blocker for my opponent's 3/1 flying Morphling. Yay! Points for the guy with too many cards!
