Visions of Dominance (Midnight Hunt Commander 75) - Rare Magic: The Gathering Card

Put a +1/+1 counter on target creature, then double the number of +1/+1 counters on it.
Flashback . This spell costs less to cast this way, where X is the greatest mana value of a commander you own on the battlefield or in the command zone. (You may cast this card from your graveyard for its flashback cost. Then exile it.)
