This enchantment enters with X charge counters on it. Remove a charge counter from this enchantment: Add one mana of any color. Activate only once each turn. At the beginning of your upkeep, if this enchantment has no charge counters on it, return it to its owner's hand.
At the beginning of each player's end step, put a charge counter on this enchantment for each untapped land that player controls. Remove a charge counter from this enchantment: Add {C}. Any player may activate this ability but only during their turn before the end step.
You and target opponent each flip a coin. Mana Clash deals 1 damage to each player whose coin comes up tails. Repeat this process until both players' coins come up heads on the same flip.
You may choose not to untap this creature during your untap step. {T}: Tap target land. It doesn't untap during its controller's untap step for as long as this creature remains tapped.
Sacrifice any number of lands, then add that much {C}.
