Ok first off, it's "half", not "have". Don't use words like extrapolated to try and sound smart if your going to mess up the easy ones like "half"
Second, just because you can't build a consistent enough deck to get a fast start doesn't mean that WE are lying
Third, we don't run 8 basics. Every good zekrom deck plays cleffa

Do you enjoy lying on the internet? You must, or at least have a serious case of confirmation bias. Cleffa seems pretty poor for getting a t1 donk ( if it's just for the t1 retreat, run manaphy). I am a more than competent deck builder and this format definitely does not have the consistency/card drawing cards to make needing an exact 6 cards reasonable (especially when 60% of the time you don't start with zekrom and require a 7th card).
I stand by what I said and offer a hearty "prove me wrong!"
