The Yu-Gi-Oh's purely defensive deck (ignoring the banned card list) is best to give up attack and cooperate with your classmates' pure offense (his own, miscellaneous cards).

I personally think that pure defense is not good. For example, if the opponent’s health is residual, what if your teammate dies? How to counterattack is to use some attack in defense

The 80% defense deck Ice Barrier is more suitable

Monster ~ Ice Barrier Strategist 1, Evangelist 2, Guardian Formation 2 Dance Ji 2 Sorcerer 1 Yutingfan 2 Monk Zheng 1

Tiger General Gandhara 1 Tiger General Laipeng 1 Tiger General Divine Weapon 1 Divine Spirit 3 Transport Troop 2 Demon Sealing Group 1

Feng Shui Master 2 Royal Knights 1 Water Shadow 2 (you can consider adding Ice Barrier Drunken Demonic Insect 3 Ice Barrier Demon Sealing Group 1 Marshmallow 1 Exhausted Undead 1) You can refer to this effect yourself

Ice Barrier Drunken Demonic Insect 3, Royal Knight with Ice Barrier 2, which can seal an opponent's monster

Magic ~ Triangular Formation of Ice Barrier 3, Ice Barrier Crest 2, Whirlwind 2, Pain of the Strong 1 Resurrection of the Dead 1, Sealing Sword of Light 1

Considering that it is defensive, it mainly uses monster traps

Traps~Magic Canister 2, Riptide Burial 1, Sand Tornado 2, Naraku Falling Cave 2 Falling Cave 1 Demonic Chain 2 Dimensional Confinement 3 Dimensional Wall 1

Soul's Rayleigh 1 (this card is relatively small) Holy Shield-Reflector Power 1 Call of the Living Dead 1 Dark Curse 3

(If you ignore the banned card, add Comet Straight Lightning and Lightning Strike. You can put 3 6th Sense Happy Feather Sweep 3. Kettle of Desire, Angel’s Charity. You can consider it.

After that, you You can also consider adding Chaos Emperor Dragon, a card that can almost kill others instantly)

It is recommended to have 10 magic cards, 25-30 traps, 30-35 monsters
