Greater Auramancy

You may cast spells from your hand without paying their mana costs.

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.

Your opponents can't search libraries. If an opponent would begin an extra turn, that player skips that turn instead.

Whenever an opponent draws a card, that player may pay 2. If the player doesn't, you create a Treasure token. (It's an artifact with "T, Sacrifice this token: Add one mana of any color.")

Activated abilities of creatures you control cost 2 less to activate. This effect can't reduce the mana in that cost to less than one mana.

Enchant creature card in a graveyard When this Aura enters, if it's on the battlefield, it loses "enchant creature card in a graveyard" and gains "enchant creature put onto the battlefield with this Aura." Return enchanted creature card to the battlefield under your control and attach this Aura to it. When this Aura leaves the battlefield, that creature's controller sacrifices it. Enchanted creature gets -1/-0.

Indestructible As long as your devotion to red is less than five, Purphoros isn't a creature. Whenever another creature you control enters, Purphoros deals 2 damage to each opponent. 2R: Creatures you control get +1/+0 until end of turn.

Whenever a creature deals damage to you, destroy it.
