WHAT BACKUPS MEAN

Why they are considered delicate

Page 4: Joel krebs  backups

Recently at dinner…

• Backups usually affect players more than

penalties do

• Players relate stronger to backups than to

other parts of the IPG

• Backups are considered to tricky as they

have to be done in a certain way

Page 5: Joel krebs  backups

Consequences

• At GPs backups have to be discussed with

a L3+

• At other tournaments it should go through

the HJ

THE GREY THEORY

What the documents tell us to do

Page 7: Joel krebs  backups

What do we backup?

• GPE – Game Rule Violation

• TE – Communication Policy Violation

• Player Miscommunication

Page 8: Joel krebs  backups

When do we backup?

If the error was discovered within a time frame in which a player could reasonably be expected to notice the error and the situation is simple enough to safely back up without too much disruption to the course of the game, the judge may get permission from the Head Judge to back up the game to the point of the error. (MIPG, p. 11)

Decision factors

YOU SHOULD CONSIDER

• Hidden information

revealed

• Time frame

• Number of decisions

made by the players

• Assumptions the players

based their decisions on

• Complexity of the backup

DO NOT CONSIDER

• Who benefits the backup

• Who had a benefit from

the original error

• Is it fair?

Page 10: Joel krebs  backups

The Golden Rule

• No partial fix

• It is very hard to foresee all consequences

– Consistency

– Protection from being biased

– No forcing players to stick to decisions done

based on wrong assumptions

Page 11: Joel krebs  backups

Exceptions for GRV

• Illegal or no choice

• Turn-based action of drawing a card

• Discard or return cards from hand

• Object in wrong zone

(if within turn and identity is known)

Page 12: Joel krebs  backups

Example Game Actions

• Simple Game Actions

– Mana Tapped

– Damage to a player

– Resolving most spells

– Destroying

permanents

– Looking at additional

cards

• Trickier Game Actions

– Draw one single card

– Passing the turn

• Difficult Game Actions

– Drawing multiple cards

– Passing more than just

one turn

– Shuffling cards known

to only one player

THE THEORY IN ACTION

On the wild floor

Page 14: Joel krebs  backups

Disclaimer

• No cheating assumed.

• Stick to the example and don‘t add stuff.

Page 15: Joel krebs  backups

Counting is hard

Player A casts

Thoughtcast for U. He

should have paid 1U.

He can not afford

paying that, unless he

hits a mana source with

the two cards.

Page 16: Joel krebs  backups

Cavern of Colorless

Player A casts a

Flinthoof Boar of two

Cavern of Souls which

both a named on

human. He attacks and

then passes the turn.

The opponent attacks

and passes the turn.

Player A draws a card.

Page 17: Joel krebs  backups

Furious Holy Battle

Player A attacks with a

3/1 Creature enchanted

with Holy Mantle. Player

B blocks with a 5/4.

Before damage he

casts Furious

Resistance. Player A

responds with Aerial

Maneuver on the

attacking creature.

Page 18: Joel krebs  backups

Don’t daze me bro!

A player casts Repeal

for X = 0 on the

opponent’s Dryad Arbor.

The opponent responds

with a Daze, returning a

Island. Then they

realize the mistake.

Page 19: Joel krebs  backups

Izzet Experiments

A player taps a fetch

land and a regular land

to cast Izzet charm in

the draw/discard-mode.

After completely

resolving the spell, the

players notice that a

fetchland has been

tapped for mana.

Page 20: Joel krebs  backups

The Concept of a Stack

• Player A casts

Ponder. Doesn‘t

shuffle. Then casts

Kozilek and draws

two cards. The

opponent stops him:

„Hey, I wanted to

counter Kozilek!“
