I found the following cards to deal with this: Aegis of the Gods/Metropolis Reformer: hexproof for yourself, which prevents opponents from targeting you with abilities/spells, amongst which are spells that force you to sacrifice your own creatures (which is one of the ways in which your opponents can still get rid of Avacyn, eventhough she's indestructible)
For example, Golgari Aristocrats
Any "as [this permanent] enters" or "[this permanent] enters with" abilities of the new token will work
Suggested cards Secure the Wastes, March of the Multitudes, and White Sun's Zenith to go from 0 to 60 (tokens) instantly Craterhoof Behemoth or Moonshaker Cavalry, Overrun, and Beastmaster Ascension as backup win conditions (or overkill tools) Welcoming Vampire, Skullclamp, and Mentor of the Meek to keep your hand full while flooding the board If you like your wins loud, lethal, and full of tiny critters punching above their weight - the altar of Jetmir is where you should worship
First edition Pokmon Cards are easily identified, because they have a special EDITION 1 logo on them
Besides, who wouldnt want a sweet Time Warp signed by Britney Spears or something
