Omega level Items: Full build sacrificed Items

I have had a few games where I ran out of things to buy. You are at full build and you need a game breaker weapon. Don't buy two of something unless you can craft it into something else. Imagine if you are past the 45 minute mark and you are hyper carrying, but if you move on the nexus, even with baron buff, you can't crack that egg. Maybe it's because SOME people on your team also think they are carrying despite their 13 deaths and who knows how much gold they have put in the enemies pocket. See Relinquished gold: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/sKfosrEE-new-stat-relinquished-gold-now-you-know-you-suck

Well go ahead and craft those two IE's into Tessai's Destroyer: Not married to the name. don't care what it does as long as it is something more that two IE's. I want this to be something that not everyone needs but if you can get it the game is over. And it should definitely unlock only after you have 6 full items (excluding sightstone) and they must consume a big ticket item like Deathcap or IE. Only need three in the game, apc, adc, and a tanky one.

I know why this item shouldn't need to exist but how many people have had games that go on so long you almost FF to be rid of it? How many boast reaching full build, running out of things to buy with 3k to spend. I KNOW PEOPLE SHOULD PUSH OBJECTIVES AND LEARN TO END THE GAME EFFICIENTLY. Tell "THEM" THAT!

** If it is going to keep happening, I WANT Tessai's Destroyer, Meteor Hammer, and Titan's Fleece.** Not married to the names.

And no these Items are not balanced. You shouldn't have fed it to Zed in the first place. BWA hahahahaha!

Ideas for actives and passives?
