Cloudstone Bloom

Whenever a nonartifact permanent you control enters, you may return another permanent you control that shares a permanent type with it to its owner's hand.

Instant and enchantment spells you cast cost less to cast.

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.
