They're decent but they could be worded a little better.

i agree and it looks like you got the idea from naruto or something =|

Again, Hades, nice cards. They're okay, but I bet you can do better!
Keep up the great work..again! haha!

I couldo better but sine i was bored i made some ninjas and i did gt toff Naruto

Amazingly better than when you first began making cards. The only changes I have are these:

The first card (changes in red):
When summoning this card you must select a card on your opponents field.This card's Level* is the same as the selected monster.and this cards ATK and DEF is also the same as the selected monster.This monster is automatically destroyed if targeted by a Magic or Trap card effect.
*"Star" was removed.


Second card, when you're removing the monsters from play, where did they start? graveyard? field? anywhere? Even if its anywhere, you have to specify that.

Third is great.

Fourth card, the words "with this card still equipped" are unneccessary.

Fifth card, when do you discard the cards?

I'ld say their goood.
