He is more than a gimmicky ruler,

he is a standard metric for FOW deckbuilding. If you are aggro, you have to be faster than him. If you are control, you have to be able to deal with him.

He not only teaches you math and timing but also keeps the degenerate decks real. It doesn't matter how many nice tricks or how expensive your deck is, Welser will remind you of the power of simplicity.

He is more than a ruler; he represents the fun side of this game, a game that has the tendency to devolve into a paper-rock-scissors game.

He deserves to be free.
