Various Grimm Decks as of July 2015.

Grimm is the most-represented ruler in competitive play as of the current and first format. I have grouped Grimm decks into three categories: burn only using Flame or Red Stones; decks using lots of Red but mixing in many colors; and decks splashing Red and using a wide range of strategies.

Here are the burn main decks.

Here are the main decks running lots of Red.

Here are the main decks splashing for Red. Notice that there is a really wide variety in card use for these decks. This to me is a sign of many viable deck building options.

The stone selections for the three types of Grimm decks vary as much as the main deck card selections. Here are the burn decks.

Here are the decks running some Red.

And here are the other decks.

The side decks are really varied. Here are the top selections.
