How to Summon Assault Mode Monsters in Yu-Gi-Oh

Powerful Assault Mode monsters are cast from your main deck by activating the trap "Assault Mode Activate" and sacrificing a corresponding synchro monster. This can be risky, as you have to first field your extra deck monster, have your trap set, and have the right card in your deck (and not hand or graveyard).

However, Assault Mode monsters are overwhelmingly strong, bearing 500 more ATK and DEF than their original forms, boosted effects, and using them doesn't take up any extra deck zones (unlike their synchro counterparts). They're a relatively small archetype, with only seven members as of this writing, but they left a big impact despite their scarcity. So, which upgraded titans reign supreme? These are the ten best Assault Mode boss monsters in Yu-Gi-Oh!

Best Assault Mode Yu-Gi-Oh Monsters

7. Red Dragon Archfiend/Assault Mode
6. Hyper Psychic Blaster/Assault Mode
5. Colossal Fighter/Assault Mode
4. Arcanite Magician/Assault Mode
3. T.G. Halberd Cannon/Assault Mode
2. Doomkaiser Dragon/Assault Mode
1. Stardust Dragon/Assault Mode

Red Dragon Archfiend/Assault Mode

Red Dragon Archfiend/Assault Mode

7. Red Dragon Archfiend/Assault Mode

ATK: 3500
DEF: 2500

While Red Dragon wields a fierce 3500 ATK, he's lower because his effect isn't a large improvement on his original, now destroying all other monsters on the field (including yours) after he attacks.

This is as dangerous to you as it is to your opponent, especially since they've likely already lost a unit after Red's strike. Still, like other Assault Mode monster, he lets you revive his original synchro form "Red Dragon Archfiend" from your graveyard if destroyed, minimizing the cost of losing him.

Hyper Psychic Blaster/Assault Mode

Hyper Psychic Blaster/Assault Mode

6. Hyper Psychic Blaster/Assault Mode

ATK: 3500
DEF: 3000

Hyper Psychic also wields 3500 ATK, and after battling a monster, you inflict damage to your opponent equal to its DEF while regaining life points equal to its ATK. A nice life-sapping ability, but one that hasn't aged especially well, as it won't impact link monsters (who don't have DEF scores).Still, like his brethren, you get to revive original synchro form "Hyper Psychic Blaster" when destroyed.

Colossal Fighter/Assault Mode

Colossal Fighter/Assault Mode

5. Colossal Fighter/Assault Mode

ATK: 3300
DEF: 1500

Colossal Fighter favors warrior-focused decks, and you can send up to two warriors from your deck to your graveyard when he arrives. This helpfully empowers his effect, lowering the ATK of all opposing monsters by 100 for each warrior in your graveyard.

Considering your two milled cards plus Fighter's original form, you should have at least three warriors milled, lowering enemy ATK by 300 or more. A nice ability, but I wish it also counted warriors in your opponent's graveyard like the standard "Colossal Fighter" does.

Arcanite Magician/Assault Mode

Arcanite Magician/Assault Mode

4. Arcanite Magician/Assault Mode

ATK: 900
DEF: 2300

Arcanite's seemingly-low ATK is boosted by 1000 per spell counter he possesses, and he arrives with two, essentially entering with 2900 power. Additionally, unlike several spell counter cards, he doesn't have a maximum limit, letting you add more with corresponding effects. And if you're willing to weaken Arcanite, he can spend two spell counters to nuke your opponent's field, destroying all spells and traps they control.

This powerful field wipe leaves your own field unscathed, but note that Arcanite's synchro form needs spellcaster-type non-tuner materials, limiting him to certain decks. Additionally, when Arcanite's Assault Mode is destroyed, you get to revive his original form from your graveyard, but since he only gains spell counters when synchro (and not special) summoned, it's a comparatively-weak rebirth.

T.G. Halberd Cannon/Assault Mode

T.G. Halberd Cannon/Assault Mode

3. T.G. Halberd Cannon/Assault Mode

ATK: 4500
DEF: 4000

Halberd is undoubtedly one of the game's strongest monsters, but he's the most difficult Assault member to field, as his synchro form requires a synchro tuner monster and two or more non-tuner synchros. Still, if you pull it off and activate Assault Mode Activate, Halberd wields an overwhelming 4500 ATK and DEF. More than that, when your opponent would summon (by any means), you can not only banish that monster, but all special summoned creatures they control, essentially shutting down their monster plays!

With this brutal ability, your opponent will soon lose unless they find a spell/trap removal, and even if they destroy Halberd, you can revive his original form, ignoring its summoning conditions.

Doomkaiser Dragon/Assault Mode

Doomkaiser Dragon/Assault Mode

2. Doomkaiser Dragon/Assault Mode

ATK: 2900
DEF: 2000

Doomkaiser is a big improve on his original form, who could special summon a zombie from your opponent's graveyard, a rather situational effect unless you knew your opponent was running undead units. Luckily, his Assault Mode upgrade now lets you special summon as many zombies as you like from both graveyards when he arrives—including his synchro counterpart!

However, the monsters have their effects negated and are destroyed at the end phase. To avoid their loss, use them as link material or for a three-tribute summon like "Beast King Barbaros", who destroys your opponent's entire field when cast. Once his effect has resolved, Doomkaiser is essentially just a beatstick, so you don't have to worry as much about protecting him, and he combos well with the numerous zombie supports we've seen in recent years.

Stardust Dragon/Assault Mode

Stardust Dragon/Assault Mode

1. Stardust Dragon/Assault Mode

ATK: 3000
DEF: 2500

Stardust works well because his original form is easy to summon (accepting any tuner/non-tuner combination) and is useful in his own right. Still, Stardust's Assault Mode wields a superior 3000 ATK, and each turn, you can send him to the graveyard to negate and destroy any opposing effect. Then, you can special summon him from your graveyard at the end phase.

Thus, unless your opponent can exceed 3000 ATK (difficult when their effects are getting negated) or banish Stardust while he's already in the graveyard, they'll be dealing with a negated effect every turn, granting you an overwhelming advantage that also protects you on your own turn. Powerful, versatile, and not too difficult to cast, I've used Stardust in several negate-oriented decks; fortunately, he's surprisingly affordable, costing well under two dollars!

How to Support Assault Mode Monsters

Since you field Assault Mode creatures with synchro monsters, you'll definitely want tuners to access your extra deck, and link monsters help provide multiple extra deck zones. Additionally, anything that can return cards from your hand or graveyard to your deck helps replace a prematurely-drawn Assault Mode card. Examples include "Plaguespreader Zombie" (who also happens to be a tuner) and "Pot of Dichotomy." You can also quickly search Assault Mode Activate from your deck using "Assault Beast."

Assault Mode cards are a fun way to summon some of the strongest monsters in the game, and new supports like "Psychic Reflector" "Assault Mode Zero" help keep them relevant in competitive play. But for now, as we eagerly await Konami's next batch of Assault Mode members, vote for your favorite card and I'll see you at our next Yu-Gi-Oh countdown!
