The future when we (Hearthstone)

In the near future, Blizzard plans to zineryt almost all the top of the deck.
"The wicked Summoner" now costs 7 mana, not 6.
"Dark Pact" now heals 4 health points and not 8.
"Obsessed footman" now costs 6 mana instead of 5.
"To arms!" now costs 5 mana instead of 4.
Now the text properties of the "focus the crystal" (the reward for the task of "Underground caves") as follows: "Until the end of the game, your creatures become 4/4 (not 5/5)".

Your assumptions that will become the new op? Gigaslot sham? Control options? Mindblast priest?
