RUSTY: Off the top of my head, I'd say you're looking at a Boeski, a Jim Brown, a Miss Daisy, two Jethros and a Leon Spinks, not to mention the biggest Ella Fitzgerald ever.
Because of how variable EDH is, I'm weirdly interested in decks that have a laser focus on doing just one thing. How do you get a 100-card singleton deck to perform as reliably as a traditional 60/4 deck? It's an interesting challenge. This is what many people might view as a mean, somehwat oppressive deck, but as you can see from my signature I have plenty of other stuff I can play that doesn't aim to shut off everyone's ability to play spells, and limiting players to non-creature spells with CMC3 or less really emphasises the importance of making early plays and finding room for cheap removal.
The vast amounts of cheap ramp and mana dorks: Help to get Sisay active on turn four.
Concordant Crossroads, Thousand-Year Elixir, Lightning Greaves: Do the same thing. With the high numbers of creatures with tap abilities, I should get more use out of Concordant Crossroads (plus, it's cool to have a World Enchantment).
Gaddock Teeg: Sisay target #1. Teeg protects my army of mana producers from most sweepers, as well as slowing a table down while leaving me mostly unaffected.
Gaea's Cradle: One of the big reasons to play Captain Sisay.
Vorinclex, Voice of Hunger: An alternative to Hokori if I've started the game with more land-searching ramp than creatures.
Kamahl, Fist of Krosa + Crovax, Ascendant Hero/Elesh Norn, Grand Cenobite: The core lock. Use Kamahl to turn your opponents' lands into creatures, which die under Crovax or Norn's anti-anthem effects.
Ulamog, the Infinite Gyre: Cleans up whatever else is left on the table. With no lands and few opportunities to play spells, plus a Vindicate on cast, Ulamog should be enough to prevent any possible recovery.
Mangara of Corondor, Helvault: Extra removal, should it be needed.
The untappers (Magewright Stone, Instill Energy, Scryb Ranger, et al) and Rings of Brighthearth/Illusionist's Bracers: What's better than a general who can tutor each turn? A general who can tutor twice each turn. Double activations of Sisay can get multiple lock pieces into play in the same turn, or just ensure land drops by searching for legendary lands.
Nature's Chosen: This card deserves a special mention because of just how it works with Sisay. You can use it to get two activations of her ability, that's the easy part. The way the untapping is worded, it can be copied with Rings of Brighthearth, so with a lot of mana you can be looking for four legends in a single turn. But there's also the second part, allowing you to untap lands (Gaea's Cradle) or creatures (Mangara of Corondor)... but only if the enchanted creature is White, which Sisay conveniently is. You couldn't get a better card to work with Sisay if you asked someone to make one up.
I draft and play EDH. If a Standard player can't understand who a card is for, it's probably for me.
I also write things about good films.
