Cloud Key Discussion

YggdrasilD49 on Bruna Voltron

5 days ago

Hey, I recently acquired Bruna and am considering building a deck around her, so thanks for the inspiration!

Have you updated this deck since then?

I really like the Cloud Key in the list, probably really helpful... Also, I was considering the blue Surveil cards from Guilds of Ravnica ( Dream Eater , Mission Briefing , Dimir Informant , Sinister Sabotage , ...), rather than Scry cards, as it can help dig through the deck while putting useful Auras in the graveyard...

Thanks again :)

There's consequence to using Helm of Awakening because there's nothing worse than seeing your opponents use it for their advantage. Cloud Key is 1 more mana, but allows you to make a quarter of your deck easier to cast and doesn't help you opponents. But your commander does a pretty good job of discounting 40% of the deck.

I dislike Clone Legion , it doesn't look as though it does much to help you other than giving you an experience counter. Blasphemous Act will help get you experience counters while staying pretty cheap to actually cast, plus probably doing more than Clone Legion ever will.

I think replacing Spell Burst is the way to go if you want to include Muddle the Mixture

Also, Insidious Will , and Psychic Rebuttal

Titak on Seal Team Sphinx. (WIP)

The deck looks pretty interesting, I have always wondered what this commander could do. I thought about trying it myself. I think that Coat of Arms and Door of Destinies are unnecessary due to all of the sphinxes being relatively strong (most are 4 or 5, some are 6+) and due to how much mana the sphinxes cost, it might be difficult to play these in addition to the sphinxes and control spells. You could consider Cloud Key to help reduce the cost of whatever you need when you draw it. As well as Call to the Kindred to help you get some free sphinxes. If you want to keep some buffs for them, consider Metallic Mimic or Adaptive Automaton . Or, if you want to play around with the Sphinx ETB effects, consider Cloudstone Curio . lastly, a little extra Mana ramp should you want it, I really enjoy Myriad Landscape . I hope this helps!

For cheap counterspells that aren't listed in your maybe board you can use Dispel , Rebuff the Wicked , Turn Aside , Unsubstantiate , Spell Pierce . Negate , Arcane Denial , Countersquall , and Imp's Mischief .

For Esper colors, there isn't much you can do for fast ramp aside from relying on faster lower costed mana rocks to makes it go faster. The other alternative route to this is going for a cost reducer route like using cards like Helm of Awakening , Jhoira's Familiar , Baral, Chief of Compliance , Cloud Key , Etherium Sculptor , Foundry Inspector , Grand Arbiter Augustin IV , and The Immortal Sun .

Hope that helps!

Just a few suggestions.

Daretti, Scrap Savant might actually be a much better commander for this deck.

Also, you may want to consider the following cards:

ClockworkSwordfish on Sai swarm

I'd recommend Etherium Sculptor and/or Cloud Key as another way to "ramp" by making your artifacts cheaper. You also might as well run Inventors' Fair as a way to occasionally tutor out whatever you need!

If you wanted to double down on the thopter production, Sharding Sphinx should be a good addition, and Retrofitter Foundry would also give you another use for them while you're at it, freely swapping out any thopters for a 4/4.

SamsWrath on Jhoira

Additional Tutors never hurts. You may want to consider: Mystical Tutor, Personal Tutor, Long-Term Plans, Reshape and Gamble.

Also, Sensei's Divining Top + Helm of Awakening or any other reducer such as Cloud Key, Semblance Anvil, Etherium Sculptor, Herald of Kozilek, Foundry Inspector and Jhoira's Familiar is amazing because it allow you to use Top to draw in response to Jhoira's draw trigger so you get 2 draws.

Words of Wind is another amazing card in Jhoira because you can draw your deck with it if you use it in conjunction with Mana Crypt, Mana Vault or Sol Ring if you have a reducer on the battlefield.

You can take a look at my Jhoira deck here: Jhoira, Weatherlight Captain - Storm
