Tahngarth

Creatures you control have hexproof. (They can't be the targets of spells or abilities your opponents control.)

At the beginning of your draw step, draw an additional card.

Each noncreature artifact you control is an artifact creature with power and toughness each equal to its mana value.

Creatures you control get +1/+0.

If a basic land you control is tapped for mana, it produces mana of a color of your choice instead of any other type.

Whenever you tap a land for mana, add one mana of any type that land produced.

Your opponents play with their hands revealed.

Sacrifice a permanent: Return target creature to its owner's hand.
