When your card is strong against another it SED (seduction) will be threefold, so your card only need a third of its adversary SED to be able to win.

That's why I want to use 2 Sexy, even if I have 3 card that will be likely to lose the 2 Sexy will likely win + the bonus card from friends it mean I can win if I'm lucky xD

The base of a trap deck is to lure people with 3 card of a attribute (you need 3 to get an attribute on your "profile"), and then use 2 card of the attribute which will be strong against the one that the attacker will be most likely to have.

The reason why you want to be attacked is because you lose nothing if you actually lose the defensive fight.

One extra detail for those that might miss the way a trap deck works:
The point is that you can get 3 win from people trying to snipe you...

Let's say you have a Sexy3/Babe2 trap deck.
When searching for opponents, somebody with a deck with Moe4+ will attack you, as you'll appear as a Sexy deck.
The lineups would be:
Moe vs Sexy
Moe vs Sexy
Moe vs Sexy
Moe vs Babe
Moe/Babe vs Babe
Giving a 3-1 result, that depending on the last card might become 4-1 or 3-2.
However, your first Sexy (and their last Moe) will be replaced by your helper's cards.

If, if, IF, you get a Babe/Moe help, and the opponent doesn't get a Sexy help, the pairings become:
Moe vs Babe/Moe
Moe vs Sexy
Moe vs Sexy
Moe/Babe vs Babe
Moe/Babe vs Babe
That's 2 wins for the opponent, and 3 up in the air. While it's a long chance, you can get a victory there.

And that's without taking into account a lot of extra tactics you can use to move the result to your favor a little bit.
