(Written) Girl who delude his friend

[Sasuke Samurai 6]

Warrior / DARK

Level: 4

ATK/DEF: 1500/300

Effect: You can Special Summon this card (from your hand) by banishing 1 Warrior-Type monster from your Field, hand or Graveyard (except "Girl who delude his friend"). Once per turn, target 1 monster you control (except "Girl who delude his friend"); Increase it's ATK and DEF by 1200. During your next Standby Phase, it's ATK and DEF become 0.

I feel sorry for her friend.

 

  Despite the relation with... its name, the card has low stats and nothing that would make it worth running in any deck. Ok, being Level 4 DARK Warrior-Type monster with low ATK/DEF makes it both searcheable & can be used by many cards, but that's all there is to it.

 

  Since it can't target itself, it would be ok to have more ATK points. Additionally, Blustering Winds is also a thing. It doesn't use your Normal Summon + is a Spell Card + the boost lasts until your next turn's Standby Phase; 3 times better.

 

  If you aim for very simple tactics with the ATK drop, you could go with Zerozerock, which is never used btw. Card of Last Will would also be interesting to use, but it's unplayabe, so...

I feel sorry for her friend.

 

Thanks. It's me.

I'll upgrade her special powers.

I have a bunch of suggestions that add up to something like this:
 

Girl Who Deludes Her Friend

DARK Level 4 (Warrior/Effect) 1500/1800

You can Special Summon this card (from your hand) by banishing 1 Warrior-Type monster from your Graveyard. While you control other monsters, your opponent cannot target this card for attacks. Once per turn, during either player's turn: You can target 1 monster you control, except this card; The target gains 600 ATK and DEF. One per turn, during either player's turn, you can activate this effect, and if you do not, activate it during the End Phase: The ATK and DEF of a monster(s) affected by this card's effect becomes 0.

It retains the searchability of a 1500 or lower monster, but has more DEF.

It only banishes from the Graveyard for her Special Summon condition (because even that is pretty easy to do).

It cannot be attacked while you have other monsters, so that your other monsters get hurt first (helping her boosting effect survive longer on the field AND having her friends be hurt first because flavor)

ATK/DEF boost was nerfed because I made it a quick effect which already worked on any of your monsters without restrictions.
I also made the "monster becomes 0" a separate effect. NOW you can trigger it off immediately at your convenience, but if you don't want to, it still goes off on its own during the End Phase so it is still mandatory, but it gives you more flexibility.
Finally, she can't affect herself but I changed it so that she can affect copies of herself (so that they can delude each other). It is the one thing I expect you to dislike the most out of my changes xD but I think balance-wise it'd be alright like this.

All in all, I went ahead and made the changes into a sample written so that you can take whatever ideas you like and see which ones you don't.
