The Tarrasque

{r}{g}{g}: Regenerate; Trample; Menace
The Tarrasque comes into play tapped, but
untaps normally during controller's next untap
phase. If The Tarrasque attacks, put a counter on
it. The Tarrasque does not untap as long as it has
one or more counters on it. A the beginning of
your upkeep phase, remove a counter from The
Tarrasque. If an effect is cast that would target
The Tarrasque, flip a coin. If heads, the effect
fails on The Tarrasque.
Destruction incarnate.
