I've been reading up on some decks (and on forums) recently and everyone keeps talking about making decks faster. That supports slow decks down and aren't typically wanted. Etc. I can see how a fast deck can allow a person to consistently claim and therefore, get some sort of an advantage on their opponent due to that extra ability.
Is there any advantage to having a slower deck with (say) more powerful cards and/or supports? If someone is claiming every turn, they are obviously getting the claim advantage on me. But, can that advantage be nullified by having a slower deck that can use the extra time/turns to good use?
I was sifting through cards the other night, trying to make some decks and I found myself putting aside almost every support because "they are slow."
Are there tournament competitive decks that use supports and other "slower" cards? Or, are they only used sparingly (if necessary)?
