U/W Tron is the final transformation of any Mono-U Tron deck that does not become R/G, once a player has amassed enough resource to acquire the components required to erect it.
This excellent deck revolves around the abuse of Gifts Ungiven and using it to dump both Unburial Rites and an appropriate target, usually Elesh Norn, Grand Cenobite or Iona, Shield of Emeria. Gifts can also be used to search out four different removal spells, to oblige the opponent to hand you an out to any situation you may be trapped in.
This deck has the same weakness in land destruction as other tron decks, however, unlike the other two, this deck can win as early as turn three should all go as planned.
In order to play this deck, a player must understand how Gifts functions. Here's how it goes:
You have the option to take up to four cards, of which your opponent selects exactly two (or one, if you only chose one) and places them into your graveyard. This double Entomb effect allows not only excellent graveyard manipulation, but also super deck thinning should you require to draw into something you cannot afford to risk having your opponent gift to you.
Gifts may also be tactically used to get you what you're missing for Tron by targeting Expedition Map, your miscellaneous tron piece and a single card you know your opponent doesn't want you to have. Mindslaver Is also in this deck as a backup win con, in the odd event your opponent survives your Norn/Iona lock.
In the odd event that your opponent doesn't autoscoop to your reanimator target, you can always win by using Eye of Ugin to search out Wurmcoil Engine or Emrakul, the Aeons Torn.
This deck is developing competitive, and isn't good enough to be tiered. That being said, when it works, IT WORKS - it's hella fun to play.
Some have tried using Griselbrand and Sheoldred, Whispering One or Jin-Gitaxias, Core Augur to more quickly destroy their opponents, however this has proven less effective than the raw control presented by both Norn and Iona.
The sideboard has been modified for the hard control and aggro-heavy meta.
