Cube based on the Mystery Booster Playtest Card set. Intent to use the playtest cards as the primary focus and build around signposts.

---

Each Color is Primary in the following broad function and playstyle.

As a high level philosophy, this cube aims to weave together Five Three color archetypes that overlap in play function and synergies.

Note: Khod, makes Tribal want to be 4 color. To resolve this does each color get an archetype to weave throughout?

1. White -> Sliver

2. Blue -> "Sea Creatures"

3. Black ->

4. Red ->

5. Green ->

6. NAYA (G/R/W) ->

7. BANT (G/W/U) ->

8. ESPER (W/U/B) ->

9. GRIXIS (R/U/B) ->

10. JUND (G/R/B) ->

11. INK (WURG) -> Tribal

To Do:

• Reduce multicolor card count -> 30 total -15
  • Hybrid cards should be reduced to 10 total
• Increase colorless card count -> 30 total + 5
• Increase non-basic Land Count -> 30 total +5 cards
• Increase Mono color cards -> 54 each +15 cards
• Sliver count should be reduced/changed for changelings where able
  • slivers are parasitic and breaks a draft, there should be sliver
    payoffs that enable changelings to be "good"
  • Plan -> Re-center slivers in GW, splash Red -> Naya
  • Counts: MH1 had 13 slivers, R/MR don't affect drafting, commons are
    2x common -> effective count: ~14 -> 14 slivers should exist,
    excluding sliv-miz/sliv-draz -> resulting in 16 total
• Add Changelings to clean up tribal -> ~14 should work based on MH1

• Metagamer : This is too specific, the card pool required to make this not a 3cmc 2/2 is absurd.

• You're in Command : Making a card a commander effectively gives it card advantage, it mostly does nothing, or it's way to strong with the correct card. This "could" be added at low risk.

• Learned Learner : This card will never function properly, having something that changes your max handsize is quite restrictive. To make this function, it would take a lot of slots,

• Chimney Goyf : This seems totally fine, its just a little over costed.

• Corrupted Key : This is a maybe, wants to be in a creature focused deck, but has a way to tap permanents. Captain of the Mists, Aboshan, Cephalid Emperor, Deceiver Exarch, Dream's Grip

• Cyclopean Titan : Maybe, it could be a reanimator target

• One with Death : Oh man.... I want to put this in. Would also need Sudden Substitution, Hive Mind to turn this into a combo

• Swarm of Locus : This can probably be added, 2 cmc 1/1 flyer is 'ok' if you have one post it's a 2/1 which isn't bad, at 3/1 it really strong.

• Witty Demon : Would you pay 3 for a 4/3 Flier? Probably yea? Also has the same condition as Yorion, Sky Nomad. Blink?

• Maro's Gone Nuts : No unplayable, you need things that double, and things you want to quadruple. Fun but ONLY a win more card.

• A Good Thing : This is mostly just fun on the face of it, but the resulting gameplay is the opponent plays defense until the caster dies in 5-6 turns. Doesn't promote a great experience for either side. So maybe.

• Graveyard Dig : Totally playable in a graveyard/ramp strategy. Arguably it's a bit over costed.

• Mirrored Lotus : In the right deck at the right time this is busted. A slot for this could be found.

• Aggressive Crag : Dual land that only works during your first main phase. Hmm

• Domesticated Watercourse : Since it becomes unattached when it changes back, this is pretty bad. 3 mana draw a card only helps in grindy games. Needs to be playtested. This can likely be added.

• Enchanted Prairie : There isn't any enchantment synergy in this cube. This is just a generic tap land. The Thriving lands fill this slot better.

• Jasconian Isle : The card is a combo piece, to make a free 3/4, you need a card that turns this into a different land type/loses all ability. Imprisoned in the moon/Song of the Dryads/Ashaya, Soul of the wilds/Cyclopean Titan. Song and Imprisoned could work, but not sure if 3 slots are worth for a card that is "mostly" dead.

• Noxious Bayou : If this cube had an infect theme, this might be ok. As is, this is just a Bayou in 99% of games. Thriving lands fill this slot better.

• Taiga Stadium : At best this is a Taiga, at worst it's a dual tap land. The Thriving lands fill this slot better.
