Of course, people will try to build control decks early on, which is actually a bit problematic, because building a control deck requires you to know what you have to answer. You can’t really do that before the format has taken some form. Another key question is what you can use as your win condition. Still, lets see what we can do.
Here’s a win condition: [scryfall]Dragonlord Silumgar[/scryfall]. Yeah, I know, an oldie, at this point, but he might be exactly what you’re looking for, because he dodges most removal in the format. Sure, [scryfall]Grasp of Darkness[/scryfall] might be a thing, so keep that in mind when thinking about blocks.
[scryfall]Deathbringer Regent[/scryfall] hasn’t seen much play and for a reason as its very expensive, but if the format is slow, it’ll do a lot of work.
