Ferocidon, it is more splashable and more aggressive.
Nightmare Shepherd heavily disappointed us, I'd comfortaby say it is the worst of the three. Braids is fun, but slow, fragile and inconsistent, so I'd test Dracolich over it. It might be worse in the long run though.
Shardless Agent. It is the narrower card of the two, as it doesn't work with counterspells, but it is a solid two for one in the right decks. Growth Spiral is not meaningfully better than the mono green options for me to cube it.
Quote from armando.zuffi »some speculations:
1 - Flay Essence vs Bone Shards? (assuming I don't run deep reaniame any aristocrats package)
2 - Dancing Sword vs Ancestral Blade vs Maul of the Skyclaves ? What order ?
3 - Meloku the Clouded Mirror vs God-Eternal Kefnet vs Iymrith, Desert Doom ? What order ?
4 - Ranger Class vs Duskwatch Recruiter ?
Maul >= Blade >> Sword. Not coming with a creature attached is a big drawback. Maul has a high initial impact, and while inefficient, does provide reach to the white deck. Blade is just some very convenient value that slots easily into decks. Reads bad but plays quite well.
