Karasu Kage have an effect, it said "If they play "Tsume", they gain Chain until the end of the game.
But it didn't even after i play Tsume all the time, i didn't get chain at all.
The only effect is that all crow gain chain if they play "Tsume".

i thought if they play tsume gain chain, "just play tsume" they gain chain, not gain chain all cards after they have tsume. did u know? effect in blog and cards in game sometime so different . _have fun and enjoy this game_
