Thbat's because I'm always telling him what's best right now, as he never actually plays the game anymore. :P
Crow Winger I think would be a better choice over Burning Mane, as almost every powerful deck I see nowadays is weight down with a lot of water creatures. with that in mind, Crow Winger can become much stronger than Burning Mane. Also, if you can get it, try to get your hands on Quixotic Hero Swine Snout. He is one godly beastfolk from Epic Dragons of Hyper Chaos that get's +3000 for every creature summoned until the end of the turn. that adds up, so summon like two bloody squito and you have a 7000 power attacker on your hands. That also applies to your opponent's summonings too, so if he's tapped they can't summon a Pyrofighter Magnus and kill it, as that would amp up his power.
My suggestion is that the deck should look like this:
Nature:
4 Bronze-Arm Tribe
4 Quixotic Hero Swine Snout
4 Crow Winger
4 Barkwhip, the Smasher
4 Mana Nexus
Dark:
4 Locomotiver
4 Bloody Squito
4 Marrow Ooze, the Twister
4 Cranium Clamp
4 Terror Pit
that would make it an even 40 cards. Though as Mullet has already said, the best deck archtype currently out is RUB.(Fire/Water/ Darkness) if anything is to be done with this along those lines, the best that can be done is BUG (Dark/Water/ Nature) but to do that would require seriously cutting back on certain cards, running no more than 18 of each civilization, plus going higher than the minimum. But whether you want to play for power, or play for fun is totally up to you.
