Yay!
What’s YOUR Zoo?
My personal favorite is Domain Zoo.
Advantages:
1. The mana base is very good, and you’re most likely going to have the full domain effect by turn 3.
2. The decklist is very expandable, so you can have things like; Doran, the Siege Tower, Bant Charm, Meddling Mage, Tidehollow Sculler, and Bob.
3. Domain is simply amazing. Tribal flames for 5 damage, Matca Rioters as a 5/5, and Might of Alara for +5/+5.
4. Great side board options. Spell Snare, Ancient Grudge, Ravenous Trap. Nix, maybe?
Disadvantages:
1. Pain (fetches, shock lands)!
2. You can’t use lands without a basic land type (no Grove of the Burnwillows + Punishing Fire).
4 advantages vs 2 disadvantages seem like good odds. Try this out some time!
