If you're willing to go for more recent cards and only want to tap creatures down, you might want to go green-white, using these guys:
Glare of Subdual
Loxodon Gatekeeper
Urza's Factory
Vitu-Ghazi, the City-Tree
All are pretty newish (2006) and should be easier to get and except for the Glare, I think, most are pretty cheap. Add in some of the tap-creatures white has, some big beaters green has and green mana acceleration, you could build a deck that doesn't deny playing creatures, but taps them down then allows you to swing quick and hard.
If you want to go full tap-down, the suggestions like opposition are, of course, better.
