Expansion / Explosion Discussion

Digger63 on Naya Reclamation

On a small scale Seal Away and Response / Resurgence work well as instants

Treasure Map  Flip, Thaumatic Compass  Flip, and Settle the Wreckage all work better with Reclamation but nothing to praise.

Where the payoff becomes borderline busted is with Zacama, Primal Calamity , Dawn of Hope , March of the Multitudes , and Electrodominance

In previous versions I tried both Skarrgan Hellkite and Biogenic Ooze . While they can steal games, they are too clunky. Circuitous Route on the other hand, is an enabler. It ramps, which sets off Compass early and pays off with Hope, Zacama, Electrodominance, and March. Turn one gate isn’t a big deal since there is nothing at the one drop spot.

With this version, of the ten games I have played B03 in Arena so far, I have won eight. (At platinum right now). Beat Azorius weeny, mono blue tempo thanks to early compass, Sultai Midrange, 3 gate decks (one Expansion / Explosion version) a jank mono black chromatic lantern, Grixis Control, and losing to Azorius weenie and Temur Reclamation.

Also, Banefire is a sorcery so that’s why I haven’t paired it with Reclamation.

I have a few ideas for you...

First, the most radical idea: Have you considered splashing just enough red to add Rhythm of the Wild ? It can add a lot of counters to your pool and really increases the efficacy of the Incubation Druid and the Growth-Chamber Guardian , plus if in play none of you creatures can be countered, which can really screw over a lot of the control decks out there.

If you do splash red, you could also add Expansion / Explosion which can pair nicely with the Wilderness Reclamation . An even better card for your deck, in my opinion, would be Electrodominance . For a seven cost Electrodominance (which you can do easily with Wilderness Reclamation and your druids) , you can sneak in your Galloping Lizrog , casting it at the end of you opponent's turn. Then it is your turn with a Simic Ascendency with 20 counters and you win.

Splashing the red could be pretty pricey if you don't have the cards for the mana base already, but if you have the cards...?

Finally, a card you might want to take a serious take a look at is Shapers of Nature . Combined with a Biomancer's Familiar , you are creating +1/+1 counters for 2 mana and drawing cards for 1 and it doesn't tap to do it. This means any extra mana from the Wilderness Reclamation can be put to great use.

Now, I'm no expert on the curves and all that for commander decks, I just know don't have too many big boys unless you're packing heavy ramp or you're playing reanimator. The curve for this deck is 15 1-drops, 21 2-drops, 13 3-drops, 10 4-drops, 4 5-drops, and 2-6 drops + 2 oddities Granted, 4 of the 1-drops, 3 of the 2-drops, and an oddity ( 2 or 4+X, listed as 9 on TappedOut Expansion / Explosion ) are all X spells. Do you typically run less than 10 4 drops?

What's particularly better than that in the 4 drop slot, skroes? I have taken the time before and went through every card with the word "Draw" in it with CMCs 1-4 in Temur colors. I added all the ones that I thought were decent in the Maybeboard. I feel like Scry 4 and then Draw 2 is better than just Draw 3 ( Harmonize / Serenity) and it also has the cheaper mana cost of a single blue instead of double green/blue. If those weren't the cards you were thinking of, let me know.

As for Baral, I never really thought of copying my mana dorks like that. Except for the time I copied Curious Homunculus  Flip because I knew it became a bigger boye with Prowess.

The main reason I referred you to the previous comments was to have you read the comment of "I don't know what to take out of the deck for new cards." I have 10 ramp cards and I think they're all at a premium value. For Wood Elves, I have two references for him. When I was building Muldrotha, I was told "For every spell, there's a creature that does it" for Wood Elves, the spell is Nature's Lore . And then on that point, I remember watching the command zone and it was talking about overrated cards. One of them was Eternal Witness because you pay an extra green mana just to get a 2/1 body instead of playing Recollect which I am now. The same thing applies to Wood Elves.

  • I considered taking Banefire out already, but there is always the chance I get it in hand and get to copy it along with its x-cost. I might change my mind on that eventually. Expansion / Explosion is only being used for expansion.
  • Planeswalkers are superfluous. I had two in the deck previously, but their effects were mostly useless and were only good for their ultimates. While, yes, they would sponge meager amounts of damage for a time being, I could instead just remove creatures that could harm me from the battlefield rather than waste card-space on planeswalkers.
  • I already have two signets. Chromatic Lantern could definitely replace Jeskai Banner , but I want it for flavor.
  • I'm fairly certain three is enough win-cons.
  • I appreciate suggestions, but your comment urks me a bit. It gives off the impression that you think I don't know how my deck works and that using your strategies would be better. I don't believe you meant it like that, but your wording could be a bit more fleshed out.
  • Thank you regardless.

What would you think of running some of the new split cards from Guilds in the list? In particular, maybe Expansion / Explosion or Justice Strike ?

This might be getting too cute, but with how aggressive the deck is, Dryad Militant might be really good graveyard hate. Can come down on turn 1 if needed but also can be a value spell with Hero of Precinct One ... that's probably way too cute though and doesn't help much against Phoenix lists.

Good point also with Geist of Saint Traft also helping to hold combo in place. I often forget his strength against combo.

How about changing Banefire into Expansion / Explosion ? It's more flexible and has a chance to actually copy counterspells or even copy your Gates Ablaze if needed be. It can serve as your wincon and draw engine.

Guild Summit won't do much in this deck as you only have 1 guildgate in the deck. Outpost Siege , while getting you cards you can cast from exile, isn't technically drawing them so doesn't trigger your commander's ability.

Brainstorm is card draw that pretty much becomes Lightning Bolt as well with this commander.

Cards like Direct Current and Bombard are not great removal in the EDH format as too much of what you want to remove is way too big for that minimal damage. If you want to keep a bolt effect, Bombard should become Spit Flame because you could potentially recur it by casting your commander or one of the handful of dragons you have in the 99.

Some EDH removal staples include: Chaos Warp , Pongify , Rapid Hybridization and Reality Shift for targeted removal and you will also want a couple of boardwipes such as Blasphemous Act , Hour of Devastation , Earthquake or Chain Reaction .

I'd cut some of the creatures like Leapfrog to go with more instants and sorceries to take advantage of your commander's last line of text. Expansion / Explosion is one I'd strongly consider.

Some cards that work with all versions of Niv: Basilisk Collar and Gorgon Flail to give his pinging ability deathtouch for boardcontrol and Curiosity is a superior engine for him.

And considering his casting cost, I'd look to add a Gilded Lotus to the deck as you could easily get stuck with not having enough of one of your colors.
