Post-release of Eldraine, it is too soon to state anything definitive about the meta, but I will put something in here as a placeholder.
We have three tournaments that are really too small, in addition to being premature: Fandom Legends, Fandom Caster's Cup and MPL Eldraine Split Sapphire Division 30/09/19.
Competitively, the finalists in all the tournaments should be considered.
- Esper Stax
- Bant Ramp
- Bant Golos
- Simic Aggro (though it doesn't look like aggro to me)
- Selesnya Adventure
