Tasmanian Devil

When Tasmanian Devil enters the battlefield,
choose target land you control. It becomes a 5/5
Elemental creature of its given color with reach
and haste until end of turn. It's still a land.
{x}{g}{g}{g}: Tasmanian Devil gets +X/+0 until
end of turn unless opponent pays {x}. This ability
can only be played during your attack step and
only after blockers have been declared.
{t}{8}: Surveil 5. Put three +1/+1 counters on
target creature with power 3 or less.
