Ok lets pretend you get these cards right off the start of a duel. Place down Toon World, get your BETD onto the field. Now Toon World says "you must pay 1000 of your own life points to activate it". No problem. Your down to 7000 life points while your opponent has 8000. This helps you when using Megamorph because it reads "If your Life Points are lower than your opponent's, the original ATK of a
monster equipped with this card is doubled. If your Life Points are higher, the original ATK is halved." Now if you didn't attack your opponent and do damage you should have less life points. Equip the Megamorph to the BETD and it powers up to 6000 Attack. You can do 6000 points of direct damage to your opponent life points at the cost of 500 of your own life points. This will leave your opponent with 2000 life points and you should be able to finish him off next turn or if he finds a way to stop you next turn, you should still be able to win after.

*Remember Toon cards can only be used when Toon World is on the Field. If Toon World is destroyed then any toon cards on the field are destroyed also.

*When using Megamorph make sure you have less life points than your opponent or else your monsters attack points are halved.
