The Top Modern Horizon Cards for CEDH
Modern Horizons has stirred a lot of talk amongst the CEDH community and some people have even renamed the set "Commander Horizons" since many of the cards seem uniquely designed for the competitive EDH format.
Below I've listed the cards that I really think will see a decent amount of play once Modern Horizons goes live.
Null rod and Stony Silence are very strong cards in CEDH, mainly due to the number of mana-ramping artifacts in the format. Once of these cards dropping early will slow down the game quite a bit. Now we have another option for artifact shut-down, and it's even on a creature.
I would expect to see this card in Blood Pod or other creature-based stax lists, like Derevi. It's cheap and effective and it is just the right type of hate for the format.
Ranger-Captain of Eos
Ranger-Captain of Eos seems like an innocuous value creature at first glance. However, it is particularly good in Flash/Hulk decks. It can be brought into play off of a Hulk, search for a Viscera Seer/Disciple of the Vault, then sacrifice itself to protect an infinite death combo kill with Zulaport Cutthroat, Blood Artist, or Disciple of the Vault (coupled with the new artifact creature). I expect to see this in some of the Thrasios-based Hulk decks in the future.
Tribute Mage is a card that I'm quite excited to see. Trinket mage sees a lot of play, but Treasure Mage, and Trophy Mage see little or no play. However, Tribute Mage hits the sweet spot with the two-mana artifact tutoring.
Two mana is particularly relevant because it gets two different, uniquely powerful cards in the format : Null Rod, and Isochron Scepter. Some other notables are Cursed Totem, Winter Orb, Grim Monolith, and a whole host of others.
I would expect to see this in mono-blue Paradox Engine/Scepter/Reversal decks. Any deck with access to black would have better tutors for the same pieces.
Lesser Masticore is really a much bigger deal than it would seem at first. By itself, it doesn't seem like a card with any type of power at all. However, it enables the use of Disciple of the Vault as a win condition in Hulk decks. This is very important because Disciple of the Vault costs one mana, whereas Zulaport Cutthroat and Blood Artist cost two mana. This allows you to get a killing loop from just one Hulk trigger.
The First Sliver
The verdict seems to be out amongst the community: The First Sliver is the best Food Chain commander to date. This comes right after the release of Niv-Mizzet, Reborn, which was set to dethrone General Tazri, which had largely replaced Prossh.
Whether you choose to use the First Sliver or not, you definitely have a lot of choices now for your Food Chain deck.
Urza, Lord High Artificer
No card in this set has been hyped quite as much as Urza. You can read tons of articles about why he's so great as a commander, but it really comes down to the fact that he's fairly mana efficient, is part of a mana engine which he can convert into drawing your whole deck. He does everything you want all in one package.
To give you the idea of his power, you can already get ahold of tuned decklists for him and he's not even out yet.
So what do you think? Did I forget any cards? Is there a combo within this set that I just didn't see? Let me know in the comments below.
