I just read the last 2 and both had some errors in the effect.

I start with Feral imp:

1. you should say in the first sentence: to special summon 1 "imp" monster [i]or[/i] 1 monster with "imp" in it's card name
2. when a monster is destroyed by battle it's automatically send to the graveyard, so paying 500 life points to do the same is a bit strange

Swordstalker:

1. you can discard [b]to[/b] cards from your hand to Negate the attack (the mistake is bold)
2. If this card [b]is[/b] attacks a monster you can (again the mistake is in bold)

Maybe you should look over the other 2 cards too, I already saw some mistakes over there too
