If you have a sizable collection of Guilds of Ravnica and Ravnica Allegiance, I can highly recommend drafting here on cubecobra and then exporting the decks to arena to play there as a direct challenge. You draft with friends or bots and play block constructed in a balanced format whenever you want.
It takes almost no extra time to set up compared to drafting on the client and is a great way to revisit these two fun, guild-focused draft environments in one concise, remastered format.

• Drafts for up to 10 players
• Cards from Guilds of Ravnica and Ravnica Allegiance
• Small additions from WAR featuring pre-invasion flavor + mechanics
• Commons have up to two copies, everything else is singleton.
• Card-rarity has mostly been kept unchanged from the original sets. The only notable change is Narcomoeba which I downshifted to common.
• Designed for drafting here and then playing on arena.
• No digital-only cards are featured.
