He helps me to traduce my poor english. Thanks a lot to him. I also have a french version available here: http://sdajce.forumactif.org/t6446-combo-victoire-tour-1-bifur-bilbon-sacquet-denethor-ii

Thanks for reading me :).

I wanted to let you know that I read through everything and I'm glad players like you are around. I couldn't ever conceive of a deck like this - and honestly would NOT try to play it, but it's great for our game that players like you are always innovating.

edit: NOT

I second Bullroarer Took. I have always enjoyed reading about Seastan's mindwarping decks and this definitely gives him a run for his money. Good on you! I only hope you don't force FFG to errata more cards...

Thanks a lot . I like to do this because it question the way the game works, how we could devoid cards from their initials purpose, or scenario from their way to challenge us. I'm not very involved in the errata debate since I'm don't have, in the end, any way to decide something. I just play cards the way they are writing, if there is way to do thing that game developer don't way to exist I have nothing to do with it. They could either don't create the cards this way or choose not to do an errata (it is neither tournament able because it is too long to execute or the best deck in a performance matter).

I have talks with Seastan since I publish this and it was really interesting ^^.
