It's strong everywhere, but it has enhanced value in archetypes that care about counters generally, +1/+1 counters specifically, proliferate tricks for multicolor brews looking to add loyalty counters for their planeswalkers, four and five-color decks, Commanders with evasion, Commanders with a power that, when increased by 1 get a faster kill, Equipment, Aura, and Voltron decks looking to get in kills with their Commander, and loads more
Dihada's a great planeswalker commander that plays to the board, fills your graveyard, ramps, and draws cards
Grim Monolith Next up is Grim Monolith
Maybe getting at pips would be a good way to getting a better look at how players are using the color pie (note to self: do this and add it)
It would be nice to see a few more solid cards in Theros Beyond Death that either help the devotion count or are devotion payoff cards like Gray Merchant of Asphodel
That said, those that are, will likely all want copies of cards like Lithoform Engine and Strionic Resonator
