{3}{R} · Enchantment · At the beginning of each upkeep, count the number of permanents. If the number is odd, until end of turn, red creatures get +1/+1 and whenever a player taps a Mountain for mana, that player adds an additional {R}. If the number is even, until end of turn, red creatures get -1/-1 and if a player taps a Mountain for mana, that Mountain produces colorless mana instead of any other type. · Illustrated by Drew Tucker · Ice Age #179 · EDHREC rank 22654 · Magic: The Gathering, MTG
