Me, the Immortal - 2GUR
Legendary Creature -- Human Rogue (Rare)
At the beginning of combat on your turn, put your choice of a +1/+1, first strike, vigilance, or menace counter on Me, the Immortal.
Counters remain on Me as it moves to any zone other than a player's hand or library.
You may cast Me from your graveyard by discarding two cards in addition to paying its other costs.
And this is how I learn Maisie Williams was in Dr Who.
