The more I play the promo card "Don't Touch" the more I like it.
Obviously it is very powerful and with the right combos is kind of OP unless your opponent uses Wrath of the Eye style effects. (I mean combing with Dr. Tofu)
In case you do not know the effect off hand, it gives you plus 1 charm and has the following text, " another character may not initiate any type of combat on this character."
This means it blocks charm and normal combat. Like I stated above it makes some cards very powerful like teaming up with Tofu to make an unbeatable team in regards to combat.
I think it's true value is the fact it can save very weak characters allowing you to make theme teams or play characters solely for their effects. This makes some characters previously to risky to play more versatile.
Plus its pretty hilarious and is on theme with 90's anime.
I give the card an 8 out of 10. If used right it can be downright powerful, if used to protect weaker characters I think it allows players to make new combos with out fear of getting steamrolled.
