A Beatdown Deck is a strong offensive Deck which concentrates on using high ATK-powered monsters to bring down the opponent's Life Points as quickly as possible. To have a successful Deck, players must be able to apply pressure to their opponent at the outset of the game before any real strategies can be employed. A common misstep in such a deck is to use powerful monsters simply for their power. A successful deck will include monsters that are not only powerful but have powerful effects to ensure the safety of your monsters.
Very few safety cards should be included in Beatdown Decks. While a select few, such as "Magic Cylinder", may be used, Spell and Trap Cards should focus on clearing the opponent's field as quickly as possible (such as with "Mirror Force", "Torrential Tribute", and other staples) in order to provide for the full potential of the monsters. Monsters should also be Summoned to the Field as quickly as possible. A further possibility is to use Trap Monsters such as "Metal Reflect Slime". Trap Monsters help you to swarm the field quickly, and can be used as tribute fodder. Cards that have a low Level but a high ATK also fit in well.
- "Evil HERO Malicious Edge" is a wonderful Level 7 monster to include due to his effect that it can be tribute summoned with one tribute when your opponent has a monster on his side of the field. It also inflicts piercing damage and can be searched with "Elemental HERO Stratos". Another powerful card that also has a powerful effect is "Super Conductor Tyranno", due to his high 3300 ATK and the ability to decrease your opponent's life points by tributing a monster on your side of the field. Another really good card is "Black Tyranno" because this card has the ability to pressure your opponent by threatening to punish him or her if he or she goes on the defensive (in which case, they should because you have a 2600 attacker on the field).
- "The Seal of Orichalcos" is an excellent card to boost the attack of all your monsters by 500, making level 4 cards such as "Alexandrite Dragon" as powerful as level 5 and 6 monsters.
- Cards such as "Blue-Eyes White Dragon" and other powerful Normal Monsters should be left out as they contribute little to the overall function of the Deck. They should only be included if your Deck is a Normal Monster Beatdown Deck, or based around one card, for example "Blue-Eyes White Dragon".
- Level Five and Six Monsters, such as the Monarchs, "Prime Material Dragon", "Jinzo" (although it prevents you from using your trap cards as well (unless if you have Amplifier)), "Dark Ruler Ha Des", "Cyber Dragon", and "White-Horned Dragon". Ideally, any monster of this level must have either an ability to be quickly summoned by itself (as such in the case of "Cyber Dragon"), have a base ATK of no less than 2400, have some sort of lockdown effect (as in the case of "Prime Material Dragon"), or an effect that can dramatically increase it's ATK (ie: "White-Horned Dragon"). Any monster with more than one tribute should be avoided unless they have a game-breaking effect (such as "Beast King Barbaros", who can be either a powerful 3000 ATK beatstick, clear the opponent's field, or be Summoned as a quick 1900 beatstick).
- A great choice for a beatdown deck would be "Injection Fairy Lily". Its effect of gaining 3,000 attack when attacking or attacked makes a death-machine against most monsters. Be sure to have cards that increase your life points, like "Solemn Wishes", so you don't wear out your life points too quickly. (**although, do consider that solemn wishes might not be as offensive in a beat-down deck)
- Along side fast summoning, putting one "Gigantes" in your deck is usually very effective. A majority of the very good beat down Monsters out there are EARTH-attribute. (ie: "Berserk Gorilla", "Goblin Attack Force" (or any variation thereof), "Chainsaw Insect", "Black Tyranno", etc...) so chances are quite high for you to have at least one EARTH Monster in your Graveyard upon Special Summoning this Monster.
- Impressive Level 4 monsters like "Gene-Warped Warwolf", "Slate Warrior", "Berserk Gorilla" and any other cards with around 1900 of more ATK. "Spear dragon" is usually one of the best bets since it has the decent 1900 attack power AND the capability of damaging your opponent if he or she happens to have a defensive position monster on the field. The downside is that it cannot attack for two turns and remains vulnerable due to it's low defense score.
- An okay substitute for "Spear Dragon" would be "Lancer Lindwurm", since it has 1800 ATK and doesn't need to be switched to defense position at the end of an attack.
- Monsters like "Chainsaw Insect", "Goblin Attack Force" and "Goblin Elite Attack Force" in conjunction with "Skill Drain".
- ATK-boosting Equip Cards like "Axe of Despair", "Mage Power" or "United We Stand".
- Use "Burden of the Mighty" to lower the attack of your opponent's monsters to inflict even more damage or to give you an edge over your opponent's monsters that would normally be more powerful than yours.
- "Shrink" and other Quick-Play Spell Cards can make your monsters stronger during Damage Calculation. To stop your opponent activating Trap Cards against the effects of your spells, play "Royal Decree" or "Trap Stun".
- Cards like "Final Attack Orders", "Battle Mania", and "Savage Colosseum" to deal more damage in battle.
- Cards that increase their power with certain effects like "Great Maju Garzett", which doubles the attack of the monster Tributed for its Summon, give you access to a greater power to beat your opponent shortly.
- Field Lockdown cards like "Chain Burst" or "Curse of Darkness" can allow the player to attack without the threat of Traps or Spells
- Cards like "Dark Snake Syndrome" and "Burning Land" to put pressure on your opponent.
- Generally, don't expect most of your monsters staying on the field for more than a few turns. Be aggressive and attack whenever possible. If you draw "Goblin Attack Force" before "Skill Drain", attack with "Goblin" and let it be destroyed when it switches to defense position. Waiting a turn or two to get "Drain" might cost you a precious window of opportunity to your opponent's life points.
- "Thunder King Rai-Oh" is an excellent addition to a beatdown deck not only because is it a level 4 monster with 1900 ATK, but it stops your opponent from searching and you can tribute it to negate a special summon, which is very effective against Synchro decks.
- If your opponent has been able to survive further through the mid-game, "Wicked Dreadroot" makes an excellent finisher by crumbling the attack strength of your opponent's monsters. If your own monsters are weakened by this effect as well, sacrifice a DARK one to "Deck Devastation Virus", enabling you to clear the field for a swift Direct Attack.
- "Level Limit - Area A" to take out their small monsters with battle damage.
- An alternative is to use "Koa'ki Meiru" monsters. These tend to have at least 1900 ATK, and some have up to 2100 ATK for no Tributes. Their downside is that you have to reveal a card in your hand but they also have powerful anti-meta effects. They can be combined with "Begone, Knave!" in order to return them to your hand so that they aren't destroyed at the end phase.
