One for all TFT game mode

Me and my 7 friends were horsing around in TFT, one of them said to all of us to go only 1 champion, and we found it very funny and I think it might be a legit game mode.

We decided to ban certain units like units that can summon a minion that is targetable.

So here are the things you can do in this mode,

You start the game not picking any units at all, your first unit is auto-assigned to you, then you start the first minion round with it, after this round you can decide to sell it for the item or sell it to buy another unit in the shop.

You can switch the one unit any time, ideally the creep round where you can get a variety of units to help you fight creeps, but you must decide which single unit to keep and build.

The ideal situation is getting 2 of the same Tier 2 units and 2 Tier 1 units of the same as the Tier 2.

We were thinking of making this a thing: When you get that unit to Tier 3, you can add a new unit to your board and start building it. The most you can get to in this mode is 2 Tier 3s.

Then when it comes down to 3 people in the game, they are forced to sell all of their units and using their Econ to start hyper rolling for 1 unit to start stacking from scratch.

Notice: Some champions can be over powered if stacked for instance:

I'm not sure if everyone likes it or not, its RNG based and it also looks at how you Econ for good units like electric the late game 3 man showdown and the itemization of units. Hopefully Rito and the community would like it and make it a legit game mode with some hot fix and balancing.
