UW Prison (Standard)

This is an anti-meta deck.

Due to the lack of enchantment-hate and native hexproof/protection it is possible to make a prison deck. The only card that can endanger this strategy is Ugin, since it can exile all our enchantments. Also, it's better to play this suite of enchantments than Claustrophobia and Pacifism, since there are plenty of Atarka's Commands in the meta and since the Command is a sac effect we can sac what we want, providing lesser drawbacks with that card being played.

So, 12+2 direct prisons that act as spot-removal, with Stasis Snare as unconditional creature-hate and Quarantine Field as Plainswalker/Enchantment hate.
8 Counterspells, being 4 of them Negate since we can pretty much ignore creatures as we can deal with them, also 2 main Dispel to deal against troublesome cards as Crackling Doom and Utter End and 2 Clash of Wills to provide another back-up against Ugin or some other top-curve card.

The deck can filter draw and hand with Jace-the-looter, and 3 Digs that can be re-used by Jace-the-Snapcaster.
Also Command to recycle Jace or gain life or do other stuff this command does.

As wincon, Gideon. Gideon can act as a token-factory or as a powerful beatdown creature. Since we can control the board, that means that 3 swings with Gideon and game is over. If we don't face much creature removal, that would be 2 swings for 14 dmg with an Ally in play.
Crackling Doom is the only card that can kill Gideon or a direct Firecraft/Ruinous Path on Gideons' turn #1, so that's why there's 2 main-deck Dispel + 2 SB.
Also be aware of Stasis Snare insta-speed.

The SB gives the deck access to Token/Aggro decks in the form of Clerics and Profaner of the Dead, that is a silver bullet against token decks.
Encase in Ice is a card that can work out more creatures in insta-speed. And also Disdainful Stoke to provide backup against Control'y decks.

This deck provides answers to the board and a very difficult-to-kill wincon, a typical prison deck not that grindy as some Sphinx's Tutelage versions or Dragon versions of control decks.
