This is the expanded version of the Summer of '19 cube.

This cube features cards that were legal in M20 Standard, during the summer of 2019; just before rotation hit with Throne of Eldraine. It is Arena playable.

That means you'll only find cards from:

• Ixalan
• Rivals of Ixalan
• Dominaria
• Core Set 19
• Guilds of Ravnica
• Ravnica Allegiance
• War of the Spark
• Core Set 20

The only small exception to this rule is the cycle of 5 allied-colored Temples. Because the enemy-colored cycle was featured in M20, I deemed it acceptable.

The cube's subject is inspired by nostalgia for the time I re-entered MTG (around the release of Dominaria and Arena). The form of a Standard Cube is inspired by @Teldolar and @F1etcher7 at Jank Diver Gaming.
