Hi!
I'm looking to build up my warrior team with samurai, reading troughout the forums i see a lot of people suggesting 6 guardian fierce for him but i really don't get it why i should do this, are those suggestions outdated? He has 1374 atk and 679 def, guardian gives him ~136atk (20% of def) and strength gives him ~206 (15% of atk). Why would i use guardian instead of power?
