Giga Berlin

{t}: Add {w} or {g}.
Giga Berlin enters the battlefield with 0 construction counters on it. Add 1 counter to it
at the beginning of your upkeep. If Giga Berlin
has 2 construction counters on it, you may exile
it and search your library for a Tesla Gigafactory
and put it into play.
For each tree they cut down, Tesla planted 3 more.
