I have little knowledge on anti-meta, so essentally I decided to pack it with the strong creatures, mostly to prevent special summoning and in the king tigers case, hold off synchrons and gadgets.
Anti-meta is based around stopping the most popular decks. The key to anti-meta is flexibility and splashability with a good side deck. The object isn't having strong monsters to stomp on their monsters, but stopping their monsters before they have a chance.
This is the list of the most recent (to my knowledge) Anti-meta deck that has won a large tourney
Monsters: 17
2 Cyber Dragon
3 Thunder King Rai-Oh
3 Doomcaliber Knight
3 Banisher of the Radiance
3 Fossil Dyna Pachycephalo
2 King Tiger Wanghu
1 Spirit Reaper
Spells: 10
3 Book of Moon
3 Smashing Ground
2 Enemy Controller
1 Heavy Storm
1 Mystical Space Typhoon
Traps: 14
1 Mirror Force
1 Solemn Judgment
1 Starlight Road
2 Royal Oppression
2 Magic Drain
2 Sakuretsu Armor
2 Bottomless Trap Hole
3 Dimensional Prison
Side Deck: 15
1 My Body as a Shield
2 Legendary Jujitsu Master
3 Pulling the Rug
2 Dust Tornado
2 Compulsory Evacuation Device
2 Crevice into the Different Dimension
1 D.D. Crow
2 Trap Hole
Extra Deck: 4
1 Chimeratech Fortress Dragon
1 Cyber Twin Dragon
1 Black Rose Dragon
1 Stardust Dragon
Cards like Thunder King and Fossil Dyno negate special summons, while Wanghu destroys any monster summoned with under 1500 atk and Doomcalibur negates effect while acting as a beat stick while Banisher removes cards from play. This deck gives the opponent a runaround as they try to get around your cards while you abuse Sakuretsu, Book of Moon, Smashing, etc.
