So, yeah. [[Freed From the Real]] is a card. What's the concept behind it? Generate enough mana, and then do something bonkers. Burn their face off, bounce all their stuff, etc.
So how do we do it?
[[Free from the Real]] enchants a creature. Often, you combine it with a creature like [[Axebane Guardian]] to generate UU or something like that multiple times over. Tap Guardian for UU (or more), untap, floating U. The state of the system has looped back around, but now you are floating additional mana. Once you have generated unbounded blue mana, you can then use that to generate unbounded mana of any other color.
So how does this specific deck work? This one doesn't have an Axebane Guardian. It actually only has 7 creatures, none of which tap for mana. Wuuuut. Wait, what's that, [[Wind Zendikon]]? Yeah, Wind Zendikon. You enchant a land and make it a 2/2. With flying. So for 2UU, enchant [[Wind Zendikon]] and [[Freed From the Real]] onto any land. Congratulations! Now you can... durdle. You tap to produce a color, and then untap the Zendikon land for U. So you gain no value. ([[Lifespark Spellbomb]] works similarly, but until end of turn). Ok, so what if the land was a Ravinca Karoo or had a [[Fertile Ground]] enchanted onto it also? Now you start generating a mana every time you activate the [[Free from the Real]]. Unbounded mana has it's advantages.
Once you have the unbounded mana, let's produce options. [[Viridian Longbow]] allows you to (as long as you float blue mana) ping someone for infinite damage. [[Flamewave Invoker]] kills the opponent in 4 activations. [[Pyromatics]] you copy like crazy. So that's a good set of options.
But wait, all of those are only 1x in the deck. You mean to tell me that your mana outlets are a 1/20 chance? Well, not really. See, the deck plays a ton of tutors.
[[Trinket Mage]]
--[[Darksteel Citadel]]
--[[Viridian Longbow]]
--[[Seat of the Synod]]
--[[Tree of Tales]]
--[[Lifespark Spellbomb]]
[[Muddle the Mixture]]
--[[Moment's Peace]]
--[[Pyromatics]]
--[[Fertile Ground]]
--[[Circle of Protection: Red]]
[[Drift of Phantasms]]
--[[Trinket Mage]] (what if you can only produce blue mana? Yeah, you tutor up the mage to tutor up the Longbow to kill them)
--[[Flamewave Invoker]]
--[[Freed from the Real]]
--[[Krosan Restorer]] (works as an Axebane Guardian, -ish)
So now you have something like 4+ ways to get each individual win con piece. 4 effective Invokers. 4 effective Pyromatics. 7 effective Viridian Longbows. All of this requires blue mana, granted, but if you for some reason only have blue mana, it's effective. And this doesn't take into account that you are playing 4x Ponder to make sure you hit some of the cards you need.
