To both empty your hand faster and ramp to the titans, you might go extra heavy on the ramp.

Dimir Signet, Mind Stone, Prismatic Lens, Arcane Signet, Charcoal Diamond, Coldsteel Heart, Corrupted Grafstone, Ebony Fly, Fellwar Stone, Fractured Powerstone, Guardian Idol, Liquimetal Torque, Obsidian Obelisk, Sky Diamond, Star Compass, Talisman of Dominance, Thought Vessel - Those are the viable 2 cmc mana rocks (Everflowing Chalice could also be played for 2 mana, but also scales more into the later stages due to Multikicker) Moonsnare Prototype and Springleaf Drum are 1 cmc but require a creature/artifact which you could tap to produce 1 mana. Sol Talisman and Mox Tantalite are also relative cheap in price.

For Land ramp, there arent that many options in Dimir, but here are the ones I would consider - Lantern of Revealing: 3 cmc Rock, that can ramp later Wayfarer's Bauble: The classic Dreamscape Artist: 2 CMC creature, that turns each card in your hand into Harrow Druidic Satchel: Not guarantees a land but not completely without value Navigation Orb: Bauble but slower Myriad Landscape: Land that fetches 2 Lands

Revel in Riches as an enchantment as is Black Market but that is kinda slow and comes relatively late Those are my suggestions for Ramp. Hope you find them helpful and GL with the deck :)

In the future, please use the Rules Q&A section of the site if you have questions about rules, cards or card interactions. That section has some added functionalities, like the ability to "mark as answer" a question and indicate you had your question resolved. I went ahead and moved it for you.

Moving on to your questions:

Question 1: You are incorrect in your understanding. Jodah provides an alternative cost for a spell, but does not change the mana cost of the spell, nor does it change the colour of a spell. A Phyrexian Hulk cast with Jodah's ability will still have a mana cost of 6 and it will still be a colorless spell.

As such, you cannot use Obsidian Obelisk's "mana of any color" ability to cast non-multicoloured cards with Jodah and you will not receive triggers on cards like Mana Cannons and Widespread Thieving.

Question 2: Faeburrow Elder only looks at color, not color identity (it does not specifically say "color identity" akin to Command Tower). As such, with only those two permanents there would not be any Black mana added.

Rhonir on Questions regarding color identity/color interaction

Good day,

I'm building a Jodah, Archmage Eternal deck and have two questions regarding the alternative cost and color identity of Jodah.

1. As far as I understand it, Jodah's ability sets the cmc for a spell to WUBRG for the action "casting". After resolving the spell gets back its former cmc and therefore colorization. Is it right that cards like Obsidian Obelisk, Mana Cannons and Widespread Thieving therefore interact with spells that I cast for WUBRG although they are monocolored since those cards interact with the "casting" action?

2. If I have those two permanents on the battlefield: Faeburrow Elder and Jodah, Archmage Eternal. Does Faeburrow Elder give me WURG (WUR from Jodah, G from Faeburrow Elder) or WUBRG from Jodah's color identity?

Many thanks in advance and I hope this is the right forum for these questions.
