This is amazing for giving your Numbers monsters more fuel to activate their abilities: for example, you could attach this card as materials to Number 17: Leviathan Dragon and have its attack stat go all the way up to 4000

But as of now, serialized versions of the 10th doctor (the only one up so far) on TCGplayer are between $600 -700
