Domain decks are not new. Most of them play Shardless Agent and Bloodbraid Elf. I have that version as well. This is not that version. This deck runs less creatures and more burn, removal, and protection while still working with General Ferrous Rokiric.
MAINBOARD:
General Ferrous Rokiric has protection from mono-colored spells { Lightning Bolt, Fatal Push, Path to Exile, Prismatic Ending } and makes a 4/4 golem every time you cast a multi-colored card. That's what this deck does. There are very few mono-colored cards mainboard, making this perfect for the General.
Territorial Kavu is the staple for all Domain decks. A 2-mana 5/5 that can draw you a card or remove a card from your opponents graveyard is a no-brainer.
With plenty of fetch lands and a land count of 23, this makes Brushfire Elemental just as large of a threat as Rokiric. Especially when you hit a land with Coiling Oracle. Coiling Oracle draws you cards when it enters the battlefield, which gives this card a slight advantage over adding something like Ice-Fang Coatyl; because if the card drawn is a land, it is put on the battlefield. That gives you the possibility of 4 lands entering the battlefield in one turn, making Brushfire Elemental a possible 9/9 in a single turn.
Lightning Helix deals damage to any target, gains you 3 life, and adds to Rokiric's army.
Boros Charm deals damage to your opponents face or their Planeswalker, gives a creature double strike, or gives the permanents you control indestructible until the end of turn. Did you read that correctly? PERMANENTS, not just creatures - all of your permanents are now indestructible. Your lands get indestructible, your artifacts get indestructible, your creatures get indestructible. ALL OF YOUR SHIT GETS INDESTRUCTIBLE. You have no idea how many people miss that small, yet VERY large detail. Remember this, just because they caught a case of the indestructible, doesn't mean they can't be exiled, have their toughness drained by cards like Dismember, or sent straight back to your hand. That would require hexproof. Speaking of which... the only mono-colored card in your main deck gives you that hexproof you so badly needed AND indestructible.
Deflecting Palm is an interesting card. It stops the damage done to you by the SOURCE (not just the creature) of your choice and redirects it back to their face. I did that against Ulamog and won the match.
Rip Apart is a fucking champ in this meta. SO many artifacts and enchants in this meta and you're running mainboard removal with the added bonus of choosing to deal damage to their creature or opponent instead. This card is invaluable in this deck.
SIDEBOARD:
Void Mirror stops all spells that were cast with no colored mana. It stops artifacts ( Mishra's Bauble, Ornithopter, Memnite, etc... ) no more Cascade, no free graveyard spells, and no free elementals ( Fury, Solitude, Grief, or Subtlety ). You get the idea.
Meddling Mage is similar to Void Mirror, but it's singular. Name a non-land card and that card can't be cast while Meddling Mage is on the battlefield.
To combat those fucking counter spells, we have Mystical Dispute.
Obsidian Charmaw to help with Tron and a little land destruction.
Path to Exile and Prismatic Ending is for added removal.
