Ageless Watcher
Artifact Creature- Golem Druid
As ~ comes into play choose a basic land type.
~ gets +1/+1 for each land you control of the chosen type.
put a -1/-1 counter on ~,
: Until end of turn whenever you tap a land of the chosen type add one mana to your mana pool of any type that land produced.

So it can have a p/t of Mountain/Mountain? I mean I dunno, but having a non-numeric p/t seems problematic...
'equal to the number of lands of the chosen type' - either in play or under your control, nut shure which he means.
I have to start proof-reading mt cards better
Weird things are happening. It can't have a power/toughness until it comes into play, so what is its p/t while it's not in play? This can be remedied by making it a 0/0 with "~ gets +1/+1 for each...". Also needs to be "as" it comes into play rather than "when".
