Why use this tool?

Full database

Every revealable monster in the game

The tool compares your monster with every Main Deck monster that has a defined ATK, using a database updated daily from YGOProDeck.

Exact rule

Higher, equal or lower ATK

Monsters with "?" ATK and Extra Deck monsters are excluded: Subspace Battle cannot reveal them.

Your decklist

Your 3 best reveals

Import your deck: the tool ranks your monsters by ATK and shows the share of the game's monsters each one beats.

What is Subspace Battle in Yu-Gi-Oh!?

Subspace Battle is a Normal Spell that applies the same effect 3 times in sequence: each player reveals 1 monster from their Deck that does not have "?" ATK.

The monster with the higher ATK is added to the hand of the player who revealed it; the monster with the lower ATK is destroyed and its owner takes 500 damage. If tied, both monsters are shuffled into the Decks.

The trade-off: for the rest of the turn, neither player can activate the effects of monsters with any of the revealed monsters' names. Keep it in mind when choosing what to reveal in your Yu-Gi-Oh! deck: the monster you win joins your hand, but its effects are locked this turn. You can only activate 1 Subspace Battle per turn.

How to use the tool

FAQ

Subspace Battle FAQ

Any monster in your Main Deck whose ATK is not "?". Extra Deck monsters are not in the Deck, so they cannot be revealed.

Yes: the monster with the lower ATK is destroyed in the Deck and sent to the GY, at the cost of 500 damage and a card for your opponent. Pick the "Send it to the GY" goal: the tool lists the monsters that beat yours and ranks your deck from the lowest ATK to the highest.

Both revealed monsters are shuffled into the Decks: nobody adds a card to their hand and nobody takes damage for that duel.

You can Summon it, but for the rest of the turn neither player can activate the effects of monsters with a revealed monster's name. This also applies to copies you already had.

The ATK printed on the card: the monster is revealed from the Deck, so no field bonus applies. That is the value the tool uses.

Yes, the tool is completely free and requires no sign-up. You can also add Subspace Battle to a deck in the deckbuilder to test it.
