Titan Dunebug

When Titan Dunebug enters the battlefield insect creatures you control get +3/+3 and gain
haste and rampage 1 (Whenever this creature
becomes blocked, it gets +1/+1 until end of turn for each
creature blocking it beyond the first.)
When Titan Dunebug dies distribute its power
and toughness as +1/+1 counters (1/1 out of its
power and toughness would become one +1/+1
counter.)
