@MangoMaster4: Saying "oil rogue is extremely popular" isn't refuting my point. It's fundamentally a combo deck built around sprint, and oil.
If you don't get any in the first 15, your combo fizzled out and you are probably gonna lose.
it is widely believed the sabertooth went extinct due to the lack of megafauna (large animals) for prey caused by the end of an ice age, since they where adapted to cold climates giving them less to live in. for game terms new patch makes his preffered pvp "prey" not a viable build.
@MangoMaster4: That's not entirely true, Echo Control, Miracle(read- Oil now) Rogue, Force of Nature Druid, and 4 apprentice mage+antonidas decks are IN the meta, even if individual examples aren't played much.
Just a remark on your HS idea, you're again talking about a deck which relies on having certain combination of cards in hand at a certain point in time and combo decks have never worked in HS. Thaurissian still seems good, but he'd seem good in any deck.
