You and Ooze Army?

Card Rules and Details

Card Type: Sorcery

Mana Cost: {3}{G}

Oracle Rules Text: Amass Oozes X, where X is the number of creature types among creatures on the battlefield. Don't count changelings. That would be ridiculous. (To amass Oozes X, put X +1/+1 counters on an Army you control. It's also an Ooze. If you don't control an Army, create a 0/0 black Ooze Army creature token first.)

Set: Unknown Event (#UG04a), Rarity: Uncommon, Artist: Unknown
