Éomer, Marshal of Rohan

Vigilance, ward 1 T: Another target creature you control gains protection from the card type of your choice until end of turn. (It can't be blocked, targeted, dealt damage, enchanted, or equipped by anything of that type.)

Whenever you cast a white spell, create a 1/1 white Human Soldier creature token. Whenever you cast a blue spell, scry 2. Whenever you cast a red spell, Aragorn deals 3 damage to target opponent. Whenever you cast a green spell, target creature gets +4/+4 until end of turn.

Flying Whenever one or more creatures deal combat damage to you, each opponent sacrifices a creature of their choice that dealt combat damage to you this turn. The Ring tempts you. Discard a card: Witch-king of Angmar gains indestructible until end of turn. Tap him.

At the beginning of your end step, put an influence counter on Palantír of Orthanc and scry 2. Then target opponent may have you draw a card. If that player doesn't, you mill X cards, where X is the number of influence counters on Palantír of Orthanc, and that player loses life equal to the total mana value of those cards.

Double strike Whenever a Goblin or Orc you control deals combat damage to a player, exile the top card of your library. You may play that card this turn.

You may cast spells this turn as though they had flash. Draw a card.

T: Add C. T: Add one mana of any color. Spend this mana only to cast a legendary spell, and that spell can't be countered.

Destroy all creatures with power 3 or greater. Then create a Food token for each creature you control. (It's an artifact with "2, T, Sacrifice this token: You gain 3 life.")
