tatsugiri pokemon card full art 186 167 Case reveal a Supporter card you find there Tatsugiri EX 142/191 Scarlet Violet

Their whole deal is that they have a special elixir which, when imbibed, will let a Time Lord regenerate into whoever they want to be (in the Doctor's case into John Hurt, aka The War Doctor)

They'd also both make great Commanders for a Disney-themed Magic deck if you're willing to play with a few printed proxies.

Rarity-restricted Cubes will be happy to have access to another one-mana 2/1, with Human and Knight both serving as potentially relevant creature types in a wider range of Cubes

Grim Draugr is a nice common creature to have with evasion
