Tezzeret the Seeker - Foil

I love this card. I use his first effect with Prototype Portal to spam my field with Steel Oversser, Rusted Relic, Contagion Engine or Parasitic Strix while I contol a black permanent. It'd also be cool to do it with Hovermyr. I also use his second effect to search out Prototype Portal or Contagion Engine. One time I was proliferating him so heavyly that I need a 20 sided dice to measure his loyalty counters

i use him with darksteel juggernaut. the deck only has artifact lands, so use his -x ability to pull out all those lands. juggernaut can be a 5/5 at least when he comes out, but is usually bigger anyway, and then keep playing the -x building him up by a maximum of two, one being from the land you dropped initially and the seconds from the -x. i own four of him. favorite planeswalker.

@arthor it says "search your library for AN artifact with converted mana cost x or less" not as many cards as you want. just one.
