Err from playing tron for about 2 years in torunies, from... lowyrn back, (im a old dude) I suggest either take out the talsmans or remove the O stone... you could easily run All is dust to whipe the board... yes the o stone stuff comes back... but you can do something better... plaing 4 sundering titans... hes a beat stick..., coming out turn 4... you dont have to karn, there are other options... also suspend lotus is very good.. it will help your turn 3/4 plays go nuts.. slaver lock is key late game, try gifts ungiven, you have lots of 1 ofs and works with academy ruins, add 3 more ugins if you can.. watch him flatten them

This is from the guy who won the last 2 pre-releases at his local store :)

Ehm...I suppose you have mixed two kind of Tron decks togheter, the GR version and the UW one...but this is really neither of them :/ Talismans are good mana acceleration and useful discards for thirst..i might reduce them for avoiding all those Kolaghan's Command but i don't think i will, they are very useful! and about the titans i suppose that four of them is way too much, they don't even trample,they have a different purpose here. About the turn four tron, well, it might happen with the perfect hand but this isn't GR so it isn't my focus there to play around it.I would love to play more ugin but he isn't an artifact, it's a serious drawback for this deck because it can't be tutored (we lack Ancient Stirrings ) and i really don't know what to substitute for him...i think it is a reeeeally good 1x tech to draw in late game after having thinned my deck with remands, repeals etc etc

Sorry FinalShifter_ but it seems that we have a completely different vision of UTron :/
