That's a good idea. Because it only rocks when mixed with Lorwyn and Shadowmoor cards. Try this.
Ancient Amphitheater
Auntie's Hovel
Gilt-Leaf Palace
Secluded Glen
Wanderwine Hub
Primal Beyond
Murmuring Bosk
Now add this.
CHANGELINGS!!!!!!!!!!!!!!!! (they all untap)
REFLECTING POOL!
Crucible of Fire! Scarblade Elite! Reaper King! Crib Swaps, Inversions, the whole 9 yards!
Now how about this changeling?
Chameleon Colossus + Crucible = 7/7 + 4 mana ability = 14/14 crusher!
not to mention 1-drop Mothdust Changeling beating 4/4. 2 Crucible = 1 smash from Colossus and its game.
Sweet, eh?
Or just run weenies with Mirror Entity...those Goblin Assault tokens? Yeah, 1 mana and they all turn into 4/4 giants. Literally giants, actually, but never mind that. 'Cuz they're also susceptible to Goatnappers.
Got some spare mana? How about 4 mana for an army of 7/7 beaters?
Yeah, have fun with them changelings there.
