Swordstalker: Stronger Attack
An easy way to give Swordstalker a strength of 3800 power attack points or more is to sacrifice all the monsters in your deck. Due to Swordstalker's special effect, it will become stronger than those of the CPU. If you have mainly a monster deck with 3 Swordstalkers, this trick will be very useful. Start by repeatedly trying to combine all of your monsters except for your Swordstalkers. Now, try to send out your Swordstalkers. It will have a power of a 6300/5900 or more. Try making multiple fusions with one card and destroy the card. For example, Zombie + Warrior = Skull knight + Hard armor = Armored Zombie. You will have 4 cards gone instead of three. Do not forget to destroy your last card with your own leader.
