You should have seen the number of people who rage quit or sent me mad comments of the apparent cancer deck. The game has gotten so complex, people get angry with some of the simplest two-card combos that can become played. Lockdown all the special summoning expected then wear them down with multiple effects like to until you win.

Statue Barrier of the Inferno X3
Statue Barrier of the Drought X3
Statue Barrier of the Torrent X3
Immortal Phoenix Gearfiend X2

Pot of Dichotomy
Pot of Extravagance X2
Supermagic Sword of Raptinus
Psychic Blade X3
Pot of Duality X2
Phantom Knights’ Fog Blade X3
Infinite Impermanence X3
Solemn Strike X3
Literally, any fifteen as they will be banished to use drawing cards or Eater of Millions
The statue barrier cards are the main cards because this stops most offensive moves before they can even happen. Using Psychic Blade, Moon Mirror Shield and Supermagic Sword of Raptinus to protect and overwhelm opponents as an all-rounder.
Then two Immortal Phoenix Gearfiend can be summoned using those equipped cards when your anti-meta effect does get destroyed and summon a new one. Or have Statue Barrier of the Inferno as to does not stop the fire attribute warrior’s effect to your advantage.
Fossil Dyna Pachycepha does the same as the barrier cards but also when flipped over it can destroy all special summoned monsters on the field.
Either stalling or countering, here are the classic hand traps like Infinite Impermanence, Ash Blossom, Messenger of Peace, Solemn Stike and Fog Blade.
Weary of Pot of Extravagance X2 and Eater of Millions as full effects of them require 18 cards in the extra deck when the limit is 15.
