Dugtrio

Burrow {2}{r}
Evolve {1}{r}: Diglett (You may pay {1}{r} and exile
Diglett rather than pay this cards mana cost. If you
do, this creature enters the battlefield with haste
and gains all counters, enchantments, and equipment
that was on Diglett.)
When you evolve Dugtrio, all creatures you
control have unblockable until end of turn.
