This deck has no 'single' strategy for winning. Here is a list of ways I have won a games:
1) Outdraw FGs hiding behind massive bonewall or Permafrost Shield while Feral Bonds heal me.
2) Massively Gigantic Otyugh. I think he's gotten above 30 attack once, but this doesn't happen often.
3) Hoard of Fireflies beat down.
4) Hoard of Mutants beat down.
5) Board control with quint/destroy mutant and 2 quint/oty, slowly killed the FG for less than 10 damage each turn.
The beauty of this deck (thanks scaredgirl, it's not my invention) is that it has multiple answers for almost any given scenario, so it is very likely that at any given point in the game you will have a card or multiple cards in your hand that can prevent you from dying and decimate your opponent. The trick of playing the deck is correctly deciding which defense and offense to play in any given situation.
As an example, if I have 1 quint, 1 elf, 1 oty, and 1 firefly queen in my hand, I must choose very carefully which one to drop, because the right choice will result in a game win, but the wrong choice will doom me to failure.
Also, deciding when to gamble on dropping a creature without quint, because if it survives it will win you the game, is key strategy. This is, by far, the most fun deck build I have played in any ccg, because I constantly have to think about what to do, what order to do it in, and when to hold onto a card for just one more turn before I use it. This deck can not win by simply dropping whatever cards you happen to be able to cast as soon as you get the quanta. In fact, the first rule of this deck is often "Do Nothing" until you are below 50 life unless forced to play a card because you would otherwise discard. It requires patience and careful strategy to play, so I love it.
