I cut it down to 390 cards, added ALL of the signets and bouncelands (and guildgates) and changed a few other such things. Since it’s been a while since I updated it, I ended up just updating it on the tab up top and it’s draftable on tappedout.net.
So why did I change to adding the bouncelands and guildgates? To put it bluntly, the mana’s really bad in the format – I was thinking about the guildgates and how they’re essentially going to be staples and that the bouncelands are, for the most part better (vulnerabilities to LD and inability to keep 1-landers aside.) Although they may be better in control decks that don’t mind the ETB clause as much, they’re still fine in aggressive decks (both bouncelands and guildgates) so I didn’t want to deprive aggressive decks those tools (even if they may be better in control decks.)
