I'm reasonably disappointed with my performance at the last PTQ with Sidisi Whip but I still think it's a strong deck, and I don't think it was tuned to its full potential for the current meta.
Going into the next few weeks, here's the updated list I'm working with:
Sultai Midrange
Creatures(21):
- 4 Satyr Wayfinder
- 4 Courser of Kruphix
- 4 Sidisi, Brood Tyrant
- 3 Torrent Elemental
- 3 Tasigur, the Golden Fang
- 3 Hornet Queen
Spells(12):
- 4 Bile Blight
- 2 Hero's Downfall
- 2 Sultai Charm
- 4 Murderous Cut
Enchantments(2):
Land(25):
- 4 Opulent Palace
- 3 Temple of Malady
- 2 Temple of Mystery
- 1 Evolving Wilds
- 4 Polluted Delta
- 3 Swamp
- 2 Island
- 1 Forest
- 1 Urborg, Tomb of Yawgmoth
- 2 Llanowar Wastes
- 2 Yavimaya Coast
Sideboard(15):
- 3 Thoughtseize
- 3 Drown in Sorrow
- 2 Crux of Fate
- 3 Disdainful Stroke
- 2 Negate
- 1 Silumgar, the Drifting Death
- 1 Sultai Charm
The format has gotten more aggressive in general, and the controlling decks have become more efficient, so I had to trim on a lot of the clunky cards to keep up with the other strategies.
Doomwake Giant is awesome when it's good, but too often it's just too slow against the matchups where you need it most, and there's a lot more worrisome x/2 creatures than Hordeling Outbursts to worry about. I dropped them to complete the set of Bile Blights.
Torrent Elemental is constantly overperforming and is especially strong against all the upgraded control decks so I added a third.
Whip is less effective than before but also less crucial to the gameplan. I don't get as many chances to run it out early when under pressure, so I trimmed a copy.
Finally, I made the manabase less painful and more consistent because I was hurting myself too much against the new aggro decks.
In the sideboard I've created a transformative control package that has generic answers against all the other decks in the format.
