No fair you have thebetterdeck

This is a modern deck, so it’s not that competitive , and I‘ve made decks that do this better, but this one is fun

True, but you can build this in historic with just a few substitutions.
Like siren's ruse/teferi's time twist over displace/essence flux
quasiduplicate over cackling counterpart
Thassa, deep dwelling over panharmicocon
Portal of Sanctuary over closet

I could see this being a fun deck, and you won't have to deal with people playing annoying cards like force of negation.

Didn’t agent of treachery get banned in historic?

I thought that was standard... OH wait, it got "suspended" that's why i missed it, you are correct.

I also don’t play MTGA

How did historical become a format ?

People had cards they couldn’t use, because they cycled out of standard, but they didn’t have all the sets for pioneer

Thanx :) it's fun how many new formats are sprouting these days.
Shows that people might be tired of the usual ones

I don’t think that is why that one started, but it’s fun to see the new formats

Ye, its the same with "Gladiator" people got tried of cards rotating out or being banned, so they just made a format that almost every card on MtgA was legal as a single copy in a 100 card deck. (except Oko, because that card is a problem)

Can't wait till halfdecks become a tourney thing.
It could be done like this.

All participants must use the same sleeves during the tournaments.

Each player must bring two decks with 30 cards in each.

It is randomly decided which half a player gets to "keep" and they must then shuffle their opponents leftover half into it.

They then play games as usual.

At the end of the game decks are split back into their original sets and given back.
Tournaments must add additional time to games to compensate for this.

That would be amazing

Players would have to adapt to the totally unexpected.
Some might build a bad deck and hope to get a good one from the opponent.
Many would probably make 5c builds in the hope of being able to play a top tuned 60 card deck.

The only problem is if copy cats somehow figured out a way to find relevance it would ruin the format

Copycats would make it interesting. They would end up with a mirrormatch 50% of the time, with 2 possible variants.
But they would have to be lucky to meet each other, because what would you copy :)

I don’t know, but I would make a elemental deck, for one as that goes good with everything

Since there are 21 decks tagged half deck, you can take a look at what was made back then

Newest version is by muktol.

If you join in, make sure that you copy the essence of the rules onto your deck so that other people can join in on the concept.

Muktol has written a nice part that can be copy pasted.

You can build two decks with 1 page, one in the main and one in the sb.

The true wonder about it is how you can build 10 of these decks and then combine them into many different "whole decks" I have hosted a couple of halfdeck nights where people got to select 1 half to throw away while getting a new half at random.

You can also remove all the lands and pile all the cards into one gigantic cube.

The challenge is to build halves that interact with absolutely all other halves.

Elementals interacts with everything well

Do they interact well with mill :)

Just build it.

There were two driving factors for building pro halfdeck.
If you were a solid player, and knew the players of the local game store you could have a number of halfdeck that would cover the entire meta. You met up, you had pre written all 49 decklists, then would walk around the game store greeting the players, taking a peek at what decks they brought, and then evaluate the entire meta from what you knew about the players. Then when lists were called on by judges, you'd give them the right list and shuffle the two halves.

The other aspect was that if 10 decks could be combined into 49 decks, then you could host plenty of fun games at your home and when the other players started to get familiar with the halves the games would only get better, and whenever a new theme was made in magic you could add a new halfdeck to the game nights. Over time just 20 half decks could cover years and years of different games, because normally players get tired of old decks, but noone gets easily tired of halfdeck because there is a feeling of change to it.

You know what else works well draw engines

Yes, they do, but don't forget that the more standalone your deckhalf is, the better it will be with everything.

A deckhalf that only discards with a deckhalf that only draws cards will be fun to play just 1 time to see the look on their face, but in the long run you want all halves to be equally lethal.

I made a decently lethal deck that self mills with basically only drawing cards, so you could most likely skip the other half
