RE: In a deck...
I like my deck to be, if not lightning-fast, to be powerful enough to stop my opponents from performing lightning-fast setups. Because, (as a result of the metagame...), popular decks are VERY fast and if you have a slow deck, you're going to get creamed before you can even do anything!! My decks also have backups(meaning things like healing cards, super scoop ups, etc.), because decks can always be unlucky, so in my opinion, why not prepare for those bad moments.
