Evolving WildsThis deck hasn't lost yet online, and I think it's pretty hard to beat. It's got a lot of ways to win, and most of them are really difficult to interrupt. I've been sweepered - no big deal. I've had someone try to overrun me with creatures - handled. Ramp has a lot of trouble getting going fast enough to survive the onslaught. It's robust against most strategies and able to exploit weaknesses in a number of builds. In fact, my #1 concern with this deck is mill, but I haven't gone up against mill yet, so I'm not sure I can't beat it too - as this deck is perfectly comfortable being the beat down deck.
Primary win con - Ridiculous card advantage using tokens,
Nantuko Husk, and
Smothering Abomination. You will draw the majority of your deck, and it's really hard - even impossible - for your opponent to keep up. From Beyond helps tutor for Abomination, as does
Evolutionary Leap, and the fact that most of your other creatures give you multiple sac options for activation of either +2/+2 from Husk, or a new creature from Leap. This deck is perfectly capable of killing t6 against a number of opponents - so being the beatdown is often not a problem at all. (I guess it's possible to totally fail your starting hand, but it's yet to happen to me sufficiently badly to be unable to recover by t2 or 3).
Secondary Win cons - this deck hardly ever wins without drawing 20+ cards. Tutelage loves that. I've managed - on multiple occasions - to mill 40+ cards in a single turn, thanks to abomination and husk. It's ridiculous how fast this deck can mill if even a single
sphinx's tutelage is in play. (2 or more is surely GG, and not in some slow piddling fashion - fast, like really fast).
Control - okay, so every once in a while this deck has to shift to control. Fortunately,
Brood Butcher (also found via leap or from beyond) is totally up to the task (thanks to endless sac creatures), as are the flesh bags, Liliana, and Ob Nixilis. Liliana, in this deck - if you ever manage to ultimate her - is absolutely ridiculous, but normally you are just happy to use her to wreck your opponent's hand, while not even caring about having to discard.
Preserving the combo - the primary combo of Husk and Abomination is well defended - thanks to Greenwarden and Liliana (who can also bring it back under most circumstances). Greenwarden is also excellent at keeping your enchantments in play - when in rare circumstances an opponent has the answers to them.
Play notes: don't worry too much about getting blue mana. You don't really need Tutelage early - don't get me wrong, if you get it t3 you'll probably win, but this deck doesn't rely on that at all. Just make sure you have at least 1 G and 1 B and you'll probably be fine. This deck doesn't really need any specific card to go. While an ideal hand has either Leap, From Beyond, or Abomination in it - you can totally win without them. So bottom line, don't kill an otherwise good looking starting hand, simply because you don't have one of those three cards or a tutelage. You'll see them soon enough in all but the worst shuffles.
Anyway, this is a super fun deck, and your opponents will 100% hate you for playing it. When it's at its best it's really hard to disrupt, when it's at its worst it's just a really solid beat down deck. Enjoy.
p.s.: suggestions are always appreciated.
Note: I'd love a way to reduce my colored requirements, so that I can fit a Rogue's Passage or two, but I can't really think of anything I'd remove, other than Lilliana.
