[TIP] "BLADE KNIGHT" The effect of "Blade Knight" increases its own ATK by 400 points when you have 1 or less card in your hand. You can Set all your Spell and Trap Cards to try and reduce your hand size down to 1 card, but if you have a hand full of Monster Cards this will not help.
You can also use Spell and Trap Cards that require you to discard a card to activate. "Magic Jammer" is a good example. Using these strategies will help you to quickly Summon a "Blade Knight" with 2000 ATK.
