Wizards of the Coast has released more information on its Commander 2019 Edition decks for Magic: The Gathering, which are scheduled to be available on August 23rd.

There are four decks slated for release:

Merciless Rage. This 100-card pre-constructed deck contains cards that are primarily Rakdos colors (Black/Red). It comes with three legendary foil commanders, one of which is the vampire Anje Falkenrath. The main theme of the deck is using the "madness" discard mechanic to cycle through your deck in search of your more powerful cards. The deck also comes with 10 double-faced tokens and box.   

Primal Genesis. It is a 100-card pre-constructed deck that features Naya colors (Red/Green/White), 10 double-sided tokens, and comes with three foil commanders. The box-top commander is a shaman, Ghired, Conclave Exile, that can create Rhino tokens and trigger the "populate" mechanic when he attacks. The theme of this deck is creating large token creature armies in an attempt to overwhelm your opponent's board state.

Mystic Intellect. This 100-card pre-constructed deck is Jeskai colors (Red/White/Blue). One of the three foil commanders included in the deck is Sevinne, the Chronoclasm, who allows you to duplicate the first instant or sorcery card cast from your graveyard each turn. This is synergistic with the "flashback" and "jump-start" mechanics found in recent Magic sets (see "Preview: 'Magic: The Gathering - Ravnica Allegiance'"). This deck also comes with 10 double-faced tokens and a box.

Faceless Menace. By far, one of the more interesting of the four themed decks because it revolves around Sultai colors (Black/Blue/Green), and synergizes with the "morph" bluff mechanic last seen in the Masters 25 set (see " 'Masters 25' Collects 25 Years of 'Magic: The Gathering'"). This 100-card pre-constructed deck features Kadena, Slinking Sorcerer as one of its three foil commander cards. Kadena reduces the cost of face-down creatures by three mana, and has a draw trigger every time a face-down creature enters the battlefield. It also comes with 10 double-faced tokens and a box.
