By the end of SV1 every single deck win condition was some kind of OTK around turn 6 or 7.
Even "slow" control decks like Dragon, Haven or Rune were OTK machines.

Also matches were decided by your opening hand.
Seeing players pray for good hand was a common sight since you literally would lose if you bricked your first tur.
