The fact that we're even discussing a colourless wishboard is just amazing haha.
Also just in case anyone was thinking about it, karn wrecks the mirror match and occasionally the Stony silence effect neuters a deck without needing to wish for anything.
Oh and (a trick from playing Sydri, galvanic genius in commander) you can animate opposing artifacts and then kill them with creature removal. Why is this relevant? Well..... I guess one of your wish targets could be liquimetal coating and you could use it like a rishadan port with karn's static ability, or destroy lands entirely with karn's +1 (which is a pretty good rate and seems viable), switch off planeswalkers for a turn, negate any permanent with an activated ability, or just kill them outright with creature removal by using karn's +1. Seems pretty versatile as an option actually.
But you're talking of a different deck here... If you go this route, you have to admit it's a very slow kill, that requires building around this interaction, and locking most of opponent's pressure, the time you get rid of his/her lands. This is for Whir Prison for example (and even Whir isn't the right shell for this), not for Tron...
I believe this Karn isn't for Tron unfortunately. Usually by turn 3, when we reach tron, we are quite often behind the clock, we want to empty the board and start deploying our stuff. This Karn does none of these.
Then the Lattice combo, well if a single creature is there -which is likely to be the case if you don't clean the board and play this Karn instead-, the combo doesn't work anymore. You ends up with Lattice in play, doing nothing useful.
Get rid of artifact lands against Affinity? It's cute when you're behind the clock, under pressure, to spend your mana and your turn killing lands rather than the 2/3 key artifacts pressuring you...
I was on the hipe for Planar Bridge, because I was thinking it could fill the role of Eye of Ugin, and even why not going 5 color PL with it, but I was wrong, the single turn lost cost me more games than the benefit of having constant threat after turn 4. This Karn looks exactly in the same spot.
Now the new Ugin, looks better already, but 1/2 of would be the maximum I guess, as the +1 isn't strong enough compare to what we have already. I rather prefer a Wurmcoil, which for me looks far better than this Ugin for 6 cmc slot. So i'm not sure it will fit...
And Blast Zone for me is the only real deal for Tron, as 1 of max, could help late game to transform tutor to usefull game plan... Atm we don't have much target for the late game, Sanctum of Ugin and Ghost Quarter are the only pieces of toolbox we have to recycle those tutors, this could fit in pretty well I guess.
