ArtistThe Pokmon Company Art Team
The first counter allows Urzas Saga to tap for colourless mana, the second adds an ability you can pay two for to put a 0/0 Construct into play that gets +1/+1 for each artifact you control, and the final ability lets you search your library for an artifact with a mana cost of 0 or 1 and then put it straight into play
Some characters will have their own effects that only trigger when those characters are at locations, like Peter Pan, Lost Boy Leader, who will have you gain lore equal to a location's lore value the first time he moves to one each turn
That restriction presents a serious obstacle to comboing with expensive Rooms in Standard (as does the negative interaction between split card mana values and mechanics such as cascade)
If you have ever browsed a pokemon mega evolution card list and noticed how many entries belong to Mewtwo, that catalog speaks directly to how central Mewtwo is to the Mega Evolution concept
