Replenish, Stiflenought, Sligh, Oath decks & Survival decks are all top tier-1 and the strongest decks in the format.
Then you have other extremely strong decks such as Goblins, Elves, Terrageddon, UW control (landstill), BW Control, Mono Black Control, Mono Blue Control, Enchantress and Tinker Fling.
That is to say though, even decks that have currently fallen off the meta such as Reanimator, Mono Blue Storm, UG Madness and Mono Black aggro can still win against the top tier-1 decks.
And also there are new decks rising in popularity such as Broccoli Soup, RG aggro (Zoo) and Aluren. Stasis also seems to be making a strong comeback given recent tournaments.
