Killer Knight

[bosteroforever]

This is a card i made very quickly, with a very simple effect. Its an anti-spellcaster monster, and needs another card to work (Last day of witch).

 

 

 

 

 

Only works with this card:

[вєgσттєη ιηѕαηιту]

Preventing your opponent from using ANY spellcasters, ever, is not only OP, but just bad card design. I get that it only works with 1 card, but that's too much. I would change it to restrict them to maybe only summining 1 Spellcaster per turn while Killer Knight is on the field, or something along those lines. This can completely lock down Spell Caster decks. On that same note, the world "play" is used incorrectly. I'm not sure how exactly to fix that, I would ask someone a little more advanced with OCG.

I fully agree. Killer Knight's effect combined with Last Day of Witch's effect makes for one seriously OP'd Spellcaster-type banner, haha. Oh, and "play" seems to Magic: The Gathering-ish. I believe you could just replace that with something along the lines of, "your opponent cannot Summon". You don't need to say "Set" along with that since saying just "Summon" automatically insinuates all types of summoning; Normal Summon, Special Summon, and Flip-Summon.

 

Here's an example of how it's effect should look after being toned down a tad:

 

Killer Knight

If "Last Day of Witch" is activated while this face-up card is on your side of the field, your opponent can only Summon 1 Spellcaster-type monster for the rest of the Duel.

 

Last Day of Witch

Either: "Pay 2000 LP, destroy all Spellcaster-type monsters your opponent controls." or: "Destroy 1 face-up Spellcaster-type monster your opponent controls."

 

Over-all a nice idea, it just needed to be toned down a bit for it to be legit. Keep em' comin'!  ;)

^How did you not know of that?

 

Anyways, the lockdown thing is unnecessary. You should change it so it acts like Summon Limit.
