Okay, so this is obviously a green-heavy deck with some blue and red splashed in. It utilizes the following creatures to generate a ton of mana:
Magus of the Candelabra + Nykthos, Shrine to Nyx
can be used to generate a bunch of green mana, because that's the primary devotion you'll see on the field.
Kiora's Follower is a solid two-drop to follow Magus of the Candelabra. Works really well for untapping Magus of the Candelabra and using that to untap Nykthox, Shrine to Nyx.
The turn 3 spell of choice is
Heartbeat of Spring
. It's subject to enchantment removal and it isn't possible to flash it in, but when turn 4 rolls around and you start casting your entire deck, or worse, Vorinclex, Voice of Hunger, things get pretty ugly.
Prophet of Kruphix
+
Zhur-Taa Ancient
where you flash in
Zhur-Taa Ancient
at the end of an opponent's turn to give you the first opportunity to abuse the extra mana.
And finally, Vorinclex, Voice of Hunger both generates an additional mana for its controller only, and penalizes opponents by a turn's worth of mana for trying to cast anything.
If you're set up with at least one of each of these important mana sources, you're racking in a ridiculous amount of mana.
Okay so now we have a huge infrastructure generating a shit ton of mana. So how do we wreak havoc? Well, here's how.
Primordial Sage
+
Prophet of Kruphix
helps you pump out creatures on your opponents turn while drawing for more creatures to keep it going, or if you're fishing for a win con it can net you that final piece of the puzzle.
Momir Vig, Simic Visionary
+
Primordial Sage
allows you to search your library for a creature and draw it after every green creature spell, no longer needing a blue spell to trigger it.
Primordial Hydra gets really big really fast, the added trample is really nice for overwhelming even the most daunting field. He doesn't always play well with Prime Speaker Zegana.
Hyrda Broodmaster is fierce, flash him in on an opponent's turn then make him monstrous for a ton of heavy-duty tokens. Or just toss him on the board early game and watch your opponent eye him wearily while looking through his hand for some removal.
Prime Speaker Zegana provides huge draw advantage.
Garruk, Caller of Beasts is pretty much guaranteed to be a target as soon as he's on the field, so it's important to keep defenses up before getting him out if you intend on using his ultimate. His benefits are kind of obvious for the most part, but what's best about him is that his -3 ability allows you to bypass counterspells. Neat-o!
Clan Defiance is a solid win-con and creature removal spell. When you can generate 40+ mana per turn, getting this off is key.
