I think this was roughly the situation, with Jade Statue as my trump
Note that theres very little of value to tutor up with Primeval Titan (just Adventurer's Inn, Eden, Seat of the Sanctum, and The Gold Saucer)
Chittering Rats is a Pauper all-star, though unplayable pretty much everywhere else

Some give flying, deathtouch, +1/+1 counters, hexproof, double strike, vigilance, haste, mana generation, sacrifice abilities, etc
