about silent?

[pitusmon]

if i do a directly attacks to my oponents life points with my silent swordsman lv5, i`m forced to special summon my silent lv7???

[cardman]

It is optional I believe.

[pitusmon]

are you sure or are you supossing?

[CHaOsYaTa]

are you sure or are you supossing?
yes it is optional.

[pitusmon]

could you explain me why? the efect of lv5 is confusing

[Blankauctions]

"Level-up" effects like this one are always optional (and the other LV monsters). SS5 can stay on the field as long as he wants, or atleast until he is destroyed/removed by another card.

[Cyber End12]

Its completely optional

you only do if you want to.

[pitusmon]

ok thanks for the aclaration

[reanimation654]

It is up to you whether or not you want to LV up

[skipper]

you can not level up if you want to then next turn do it
