Hall of Gemstone Discussion

OmniDreamer on Forest for the Wicked (Kamahl & Kodama EDH)

2 weeks ago

Something else I just realized that I like about Springbloom Druid in this deck is that it provides 3 triggers for Kodama in addition to the two landfall triggers for other permanents with landfall effects. Also forgot to mention Elvish Reclaimer as a nice land tutor that can be activated during an opponent's turn to start the Ghost Town chain with landfall token generators.

Because of how quickly Kodama can chain lands onto the field I feel like you could add more cards that help put lots of land into your hand like:

I mean if you drastically shifted the playstyle of the deck it would be fun to run Sasaya, Orochi Ascendant  Flip in the 99 for the exponential basic forest mana. I'd still use your partners as the commanders and have more basic forest in the deck with more effects to drop lands into play like Burgeoning

Also if you just want to really annoy your opponents.

  • Collector Ouphe great if you don't have many artifact abilities.
  • Hall of Gemstone green decks tend to just play stuff on their own turn so locking others down to a single color doesn't usually affect you.
  • City of Solitude this can be good for you if you usually need people to leave you alone on your turn, but detrimental if you need to respond on an opponents turn. Note: this does not even allow people to tap for mana on an opponent's turn.

Hall of Gemstone was up for consideration but with Dockside Extortionist and Smothering Tithe are mainstays and are a middle finger to any sort of land base hate like Blood Moon or Hall of Gemstone; I went for the more artifact based hate like the ouphe and Karn.

You need Hall of Gemstone. It is doubly vicious with collector ouphe in your deck.

Edit: Hall will stop consultation/ thassa combo most of the time unless they have mana dork or artifact fixing (which you already have artifact fixing hate).

Blighted Woodland and Myriad Landscape probably would fit in here somewhere, offering lands that count as a ramp spell. Hall of Gemstone is probably handy to protect vs counters, maybe Defense Grid too? Depends on your meta if people run a lot of instants, because you've only got 10. Hall also neuters many 4 or 5 color decks, again meta issue.

Hall of Gemstone and Collector Ouphe type spells.

I have change Hall of Gemstone for Beast Within for more aggressiveness and versatility. Also (and mostly) because Hall of Gemstone trigger so much hate. The change of sideboard card Vorinclex, Voice of Hunger for Allosaurus Shepherd is also based on the hate factor by changing an alternate wincon with protection for the main wincon.

I have also change Wurmcalling for Moment's Peace. The Buyback effect and the fact that we want to put the most mana possible into the X effect are counter productive with the draw rate of the deck. I'm also trying to re-balance the offensive/defensive capacity.
