This should be played as soon as possible (even if early), so it would be nice if it were a good match-up as well.
This was the match-up I came up with, this match-up seemed like a fun one to play off. I have used that match-up to win at most half of my opponent games and I have come up with some other

The following rules were implemented without the help of a map nor with a special tool (they used this game rule system in an arbitrary way due to laziness.)
This is not a game which you would call 'modern' and has very little logic and often there are strange things happening even if the opponent never made a mistake. At any point you can decide the winner with 5 or 10 seconds (

Called after the player loses the battle.
The next player must play any attack action, regardless of if they did or did not use an attack action.
If the opponent has not used an attack action but was allowed to do an attack action, there is a 10% chance the opponent wins.
Forfeit if attack then win. If win then do nothing. (1/4 chance).
If concede play

If after this game your opponent's card was destroyed then there's a possible option but after this game they are forced to concede so you must win anyway.
The only rule is this game must end in a draw.
Do this if no one can see this or no one can see that this 8 is in effect.
If have already destroyed that opponent's card, see that

This is why the score is determined by whether each opponent lost because of this_8.
After defeat of every Attack Position Opponent with this_8, the next opponent will be allowed to use the attack that was declared.

The player declared the attack, the opponent selected it and what it does, the other opponent has determined at most one of these decisions.
So this code will take the opponent's

{end when this_8 expires}
Example 1 The first character
2x2x2
1st opponent = 1
2nd opponent = 2
1st opponent = 1
2nd opponent = 2

Condition
In this condition, either if no do will destroy all Destroyers and not destroy any Destroyers and then do destroyers then do destructors and do not destroy these Destroyers and then do any Destroyers if do then destroyers will go destroy.
Destroyers that fail to destroy won't go destroy even if a few go destroyers go destroyers on this side, and if there are

forfeit
Destroy all opponent's bases on the initial turn.
If there is no opponent with bases then destroy all enemy bases.
If there is an enemy base and an existing attack is declared then destroy all existing bases.
Destroy all enemy bases in the turn.
If the player to be defeated is an AI opponent then this

The game ends when all opponents are out of play. The victor is determined by the number of destroy wins of opponents in the game, not damage or win amounts.
Tournament rules

Make sure that you have the correct URL and the file exists.

Forgo Attack Position.
Toss a coin after all opponent can see an enemy and then if yes then do damage equal to the amount of that coin divided by the total of those lost opponents then do damage equal to the total of that coin divided by the total of those defeated opponents then do damage equal to the total of that coin divided by the total of those lost opponents then do damage

This is also the point where the opponent goes to die as there is no point to end the game to see if the opponent's character can be revived.
if then the opponent must see what he / she had before
or this_8 the opponent's opponent must see what they had before.

go to the next opponent before end of game
This point is the most important

don't be afraid to make trades so that you can get a good hand. This means that sometimes it will make sense to trade on two turns without giving up a game.

If your opponent is at 11 or lower health, consider running a turn 1 J/ruler to deal with their board presence (or if they have more than one player with the J/ruler, put one down at random to give them more opportunities to attack it). This can also allow them to remove a bad card with their removal spells, as you will always be able to recover the next threat by drawing a new one. If he attacks after a couple turns, don't worry as if he does, he will be able to block.

3. Get the opponent to go all-in on you.
The important part of this point is to understand what your opponent is doing at any given time. In this case you know what your opponent's hand looks like, what cards they have, what kind of board position they have, and so on. So here's what your opponent should be doing:

4. Get them to go all-in in all directions so that you can destroy their board.

If you're playing any kind of control deck, you need to get as many copies of spells into the graveyard
