"Toon Summoned Skull", "Manga Ryu-Ran", "Toon Mermaid" and "Blue-Eyes Toon Dragon" inside "Toon Kingdom"
In the anime, the "Toon" monsters are immune to the attacks of the opponent's non-Toon monsters while its controller also controls "Toon World".
The main strategy of a Toon Deck is direct attacks on your opponent. "Toon World" is required for Toons to attack your opponent directly while they have monsters on their side of the field."Toon Table of Contents" can aid you in adding Toon cards to your hand.
Since most Toon monsters can be Special Summoned from the hand by their own effect if "Toon World" is present on the field, you can Summon more than one Toon in a turn. Although most of the Level 5 or higher Toon Monsters require Tributes for their Special Summon, as the Tributes are not Tributes for a Tribute Summon, you can Tribute Token Monsters generated from cards like "Scapegoat" and "Fires of Doomsday".
Using "Phantom Skyblaster" can generate Skyblaster Tokens, which are useful as Tributes for Level 5 and above Toons. "Phantom Skyblaster" also provides further damage with its effect in combination with "Toon Cannon Soldier's" effect, while giving you access to "Number 66: Master Key Beetle" to further protect your "Toon World".
Since a lot of the Toon monsters can be Special Summoned when "Toon World" is on the field you can create a big swarm of monsters for a fast Xyz Summon or Summon a Tuner monster for a fast Synchro Summon.
"Toon Gemini Elf" and "Toon Masked Sorcerer" can maintain hand control, because, while you control "Toon World", their effects will trigger if they launch direct attacks ("Toon Gemini Elf" forces your opponent to discard a random card from their hand, while "Toon Masked Sorcerer" allows you to draw a card if it inflicts Battle Damage).
Toon monsters are very reliant on "Toon World" and most of them are destroyed when "Toon World" is destroyed. "Cursed Seal of the Forbidden Spell" renders your Deck useless. Cards like "Stardust Dragon", "Dark Bribe", "Card Guard", "Carrierroid" and "Solemn Judgment" can negate card destruction effects. However, if the "Toon World" would leave the field by means other than destruction, such as with "Giant Trunade" or for the cost of "Anteatereatingant", then the Toon monsters would not be destroyed.
It is also possible to chain a "Emergency Provisions" to your "Toon World", and, in this way, you can "evade" the destruction of your Toon monsters. However, since "Toon World" is now no longer on the field, Class C Toons lose their direct attack effects. "Starlight Road" is very useful against mass destruction cards that pose a threat against "Toon World", such as "Heavy Storm" and "Mobius the Frost Monarch".
"Forbidden Chalice" can also be used to negate the effect of a Toon monster, so it will not be destroyed when "Toon World" is destroyed, and it can also negate the Summoning Conditions of Toons, so they can attack during the turn they are Summoned. However, Toons will also lose their direct attack effects. "Book of Moon" can be used to flip a Toon monster face-down and thus saving it from destruction when "Toon World" is destroyed; however, it will need to wait an additional turn to commence an attack.
"Vengeful Bog Spirit" can be very useful in a Toon Deck, because, while it will not impair your Toons much (since they cannot attack when they are Summoned anyway), it will impair your opponent greatly. "Future Visions" can also be included in a Toon Deck, since most Toon monsters are considered Special Summons, which are unaffected by "Future Visions". "Creature Swap" is also very good in a Toon Deck, because your opponent will be forced to attack your Toon monsters, if you swap a Toon.
It is not easy to keep the Toons long enough on the for their Direct attack effect to take effect. "Gravity Bind" is always a good card to stall as it gives your monsters time to 'warm-up' so to speak. But as the Toons are all Level 4 or above "Gravity Bind" may not work as it prevents them from attacking. "Nightmare's Steelcage" may be more useful as it gives you the time to activate your Toon's effect and "Nightmare's Steelcage" leaves the field two Turn's later enabling you to play their Direct attack effect.
"Cursed Seal of the Forbidden Spell" can cripple a Toon deck as it destroys Toon World and it disables the use of it for the rest of the duel. Be sure to have "Trap Stun", "Seven Tools of the Bandit" or even "Magic Jammer" to be at least in your Side Deck to keep your Toons safe.
