I'm going to be off the boards for a while thanks to school, and the bile has been building up. All of you are assuming things that have absolutely no basis. Samurai's POW being halved for Roxas as a friend (should either be 0 if it doesn't count or 12). Form discards. Form cards not being player cards, despite the rulebook saying they are.
Basically, what I'm saying is that there shouldn't be questions on here that go to 2 pages asking "when can I discard a form card" when, right there in the rulebook, it says "you may discard a form card at ANY time." You guys all need to read cards and the rulebook before making assumptions and arguing over them.
And the answer, when someone asks "why can I do that, but not this" is because the rulebook says so. The rules don't say "you may use Beast at any time," we had a ruling, he can only be used on your turn. Form cards are specifically allowed to be discarded at any time via a rulebook effect.
I know it's hard,but I'm asking you to actually look at, read, and figure things out for yourselves instead of coming on here, saying "it should be this way, why isn't it," and having not read the rulebook (form cards, CowG+Cerberus) or the entire card (Diz).
