Sphinx’s Decree Discussion

multimedia on Azor, the Lawbringer deck types

7 months ago

Consider Azor, the Lawbringer with Brago, King Eternal ?

To repeatedly blink Azor to abuse his ETB Sphinx’s Decree and blink mana rocks to abuse his repeatable Sphinx's Revelation . When Azor attacks tap all your mana rocks for mana. Use that mana to activate Azor's ability; draw cards and gain life. When combat damage step is done and you did damage to an opponent trigger Brago. Untap all your mana rocks by blinking them; able to use them again for mana during your second main phase or leave them to use to cast instant spells during your opponents' turns.

If you like white and/or blue Planeswalkers and already have them they're also good with Brago and blink.

If you're looking for cuts I'd suggest Mavren Fein, Dusk Apostle and Revitalize. Mavren is gonna do nothing when you don't have profitable attacks and even at his best a 1/1s a turn ain't that big of a deal a lot of the time. As for Revitalize I don't think the lifegain triggers matter enough that you'd want this (4cmc draw 2 with Dawn of Hope and 2cmc +1/+1 and card with Ajani's Pridemate). After that maybe Ajani's Welcome and Bishop's Soldier but from there the rest of the deck starts looking essential.

20 lands seems a little low tbh. Speaking of lands, a couple Zhalfirin Void is a freeroll with your color requirements.

Sideboardwise:

  1. I don't think Sphinx’s Decree works how you think it does. It stops them playing spells on THEIR turn and isn't going to work like a Silence effect to let you combo.

  2. Against burn Shield Mare is backbreaking and I also quite like Healing Grace as it can counter Risk Factor quite effectively and can also protect your must answer creatures from removal while also gaining life.

  3. I have a crazy theory that Tocatli Honor Guard is better than Sentinel Totem against the graveyard deck. Would you rather shut down their entire game plan (branchwalker, jadelight, chups, findbroker, izoni, wildgrowth, glowspore, supplier and even bugler and autumn in white builds) or fizzle Find / Finality one time? Obviously it dies to more stuff and Ajani's Welcome might have to be boarded out but personally I think it's worth it. The other consideration is it won't work against anything Arclight Phoenix related but that's a lot less common I think. Ok, rant over ;).

Anyway good luck. Hopefully with the rotation this combo gets more viable in constructed.

Sphinx’s Decree was the only terrible card in your list.

Now, Failure // Comply is your only bad card.

The rest of your deck is made up of perfectly playabke cards, IMO

Your curve isn't perfect, but you have something to work with here.

Sphinx’s Decree is pretty bad

Love the deck concept, an alternative to Hope of Ghirapur you could run Sphinx’s Decree which is functionally a duress in white, which would work well if you ran the Teferi, Hero of Dominaria: +1 teferi, cast decree, go off in their upkeep.

A thought accrued... Perhaps a couple Sphinx’s Decree could be in the Maybeboard\Sideboard? Since Sorcerous Spyglass lets you see the hand once, you may be able to anticipate when you don't want them casting any instant or sorceries. Just a thought...

mrfab13 there is Hour of Revelation for remove lich. Maybe you can consider a splash of blue for some counters or play Axis of Mortality when you have 8 manas and play it with Sphinx’s Decree
