Guildmages' Forum - Guilds of Ravnica (Rare) [GRN-250]

Guildmages' Forum is a land from the Guilds of Ravnica set that produces colourless mana and can generate mana of any colour for a cost. When spent on a multicoloured creature spell, the creature enters the battlefield with an additional +1/+1 counter, making it beneficial for decks that focus on multicoloured strategies. However, it primarily provides just one colourless mana, which may limit its immediate utility in mono-coloured builds.
